The present invention is directed to stable emulsions comprising polyolefines, in particular polyisobutene, the process to obtain said emulsions and the use of said emulsions.
Polyolefines and in particular polyisobutene(s) are useful ingredients in a lot of technical applications. It is, however, still difficult to obtain stable emulsions comprising such polyolefine(s) and water. There is always a need to add either surfactant or huge amounts of additional polymer, see e.g. DE19505100, WO2007/014915 (Aqueous dispersions and their use) and WO2007/042454 (Process for producing aqueous emulsions and dispersions)
Therefore it is one goal of the present invention to provide an emulsion containing polyolefine(s) and water, which is stable.
This goal is surprisingly reached by the emulsions according to claims 1 to 10. The process of producing a stable emulsion as well as the use of such an emulsion according to claims 11 and 12 respectively form additional aspects of the present invention.
Thus the present invention is directed to an emulsion comprising
a) polyolefine(s) in an amount of from 2 to 75 mass %,
b) polymer(s) Px in an amount of from 0.05 to 40 mass %,
c) oil(s) Ox in an amount of from 0 to 25 mass %,
d) surfactant(s) Sx in an amount of from 0 to 25 mass %,
e) additive(s) Ax in an amount of from 0 to 20 mass % and
f) water in an amount of from 10 to 97.95 mass %,
based on the total mass of the emulsion.
The emulsion can consist of components a), b) and f), in which case the amounts add up to 100 mass %,—such an emulsion forms a preferred embodiment of the present invention. The emulsion can also contain components a), b) and f) as well as additional components. Emulsions, which in addition to components a), b) and f) also contain components c) and/or d) and/or e) form one preferred embodiment of the invention. The inventive emulsion may also contain other components.
With regard to the amounts, in which the respective compounds are present in the emulsion there exist preferred ranges. Thus an emulsion according to the invention, wherein the components independently of each other are present in amounts of:
a) polyolefine(s) in an amount of from 5 to 50 mass %,
b) polymer(s) Px in an amount of from 0.5 to 30 mass %,
c) oil(s) Ox in an amount of from 0.1 to 25 mass %,
d) surfactant(s) Sx in an amount of from 0.1 to 20 mass %,
e) additive(s) Ax in an amount of from 0.1 to 15 mass % and
f) water in an amount of from 30 to 90 mass %,
based on the total mass of the emulsion, forms a preferred embodiment of the present invention.
Even more preferred is an emulsion, wherein the components independently of each other are present in amounts of:
a) polyolefine(s) in an amount of from 10 to 40 mass %,
b) polymer(s) Px in an amount of from 0.5 to 15 mass %,
c) oil(s) Ox in an amount of from 5 to 20 mass %,
d) surfactant(s) Sx in an amount of from 0,1 to 15 mass %,
e) additive(s) Ax in an amount of from 1 to 10 mass % and
f) water in an amount of from 40 to 85 mass %,
based on the total mass of the emulsion.
And most preferred is an emulsion, wherein the components independently of each other are present in amounts of:
a) polyolefine(s) in an amount of from 15 to 30 mass %,

e) additive(s) Ax in an amount of from 2 to 8 mass % and
f) water in an amount of from 50 to 80 mass %,
based on the total mass of the emulsion.

Preferred are the homopolymers of acrylic acid and the copolymers of acrylic acid with maleic acid. The oligomeric and polymeric carbonic acids preferably are used as acids or as sodium salts.
Chelating agents are compounds, which can bind cat ions. They can be used to reduce water hardness and to precipitate heavy metals. Examples of complexing agents are: NTA, EDTA, MGDA, DTPA, DTPMP, IDS, HEDP, β-ADA, GLDA, citric acid, oxodisuccinic acid and butanetetracarbonic acid. The advantage of the use of these compounds lies in the fact that many compounds, which serve as cleaning agents, are more active in soft water. In addition to that scaling can be reduced or even be avoided. By using such compounds there is no need to dry a cleaned surface. This is an advantage in the work flow.
Useful anti greying agents are e.g. carboxymethylcellulose and graft polymers of vinyl acetate on polyethylene glycol.
Useful bleaching agents are e.g. adducts of hydrogenperoxide at inorganic salts, such as sodium perborate-monohydrate, sodium perborate-tetrahydrate and sodium carbonate-perhydrate, and percarbonic acids, such as phthalimidopercapronic acid.
As bleach activators compounds such as N,N,N′,N′-tetraacetylethylendiamine (TAED), sodium-p-nonanoyloxybenzenesulfonate and N-methylmorpholiniumacetonitrilemethylsulfate are useful.
Useful enzymes are e.g. proteases, lipases, amylases, cellulases, mannanases, oxidases and peroxidases.
Useful as dye transfer inhibitors are e.g. homo-, co- and graft-polymers of 1-vinylpyrrolidone, 1-vinylimidazol or 4-vinylpyridine-N-oxide. Also homo- and copolymers of 4-vinylpyridin, which have been treated with chloro acetic acid are useful dye transfer inhibitors.
Biozides are compounds, which kill bacteria. An example of a biozide is glutaric aldehyde. The advantage of the use of biozides is that the spreading of pathogenic germs is counteracted.
Hydrotropes are compounds which enhance the solubility of the surfactant/the surfactants in the chemical composition. An example is: Cumolsulfonate.
Thickeners are compounds, which enhance the viscosity of the chemical composition. Non-limiting examples of thickeners are: polyacrylates and hydrophobically modified polyacrylates. The advantage of the use of thickeners is, that liquids having a higher viscosity have a longer residence time on the surface to be treated in the cases this surface is inclined or even vertical. This leads to an enhanced time of interaction.
An emulsion, which has a content of organic solvent below 50 mg/kg of emulsion is particularly preferred.
An emulsion according as described above, which is stable for more than 2 days according to the phase-stability-test forms a preferred embodiment of the present invention.
Phase-Stability-Test:
The stability of the emulsion is tested by visual inspection via the phase-stability-test. After preparation, the emulsion is stored in a closed graduated cylinder (Hirschmann Duran 100 ml volume, NS24/29) at room temperature without agitation. After 1 h, 4 h, 24 h and 48 h, the emulsion is inspected for phase separation.
A process for making an emulsion as described above, comprising the steps of: combining polyolefine(s), polymer(s) Px, water and optionally oil(s) Ox, surfactant(s) Sx and additives Ax and homogenizing said components in a mechanical mixer without the use of a solvent forms another aspect of the present invention.
Regarding the details of the process different versions are possible.
The emulsions can be prepared by processes known in the literature, for example in Heusch, R., “Ullmann's Encyclopedia of Industrial Chemistry”, Chapter “Emulsions”, 1-47, Wiley-VCH, 2000 (DOI: 10.1002114356007.a09—297) or in Kostansek, E., “Kirk-Othmer Encyclopedia of Chemical Technology”, Vol. 10, 113-133, Chapter “Emulsions”, John Wiley & Sons 2003 (DOI: 10.1002/0471238961.-0513211206180902.a01.pub2).
Suitable emulsifying machines are for example high-speed stirrers, agitation or impact machines, emulsifier centrifuges, colloid mills, metering pumps (atomizers), vibrators, ultrasonic generators and homogenizers.
In one preferred embodiment of the invention, the preparation of the emulsion is achieved via a solvent-free route (a solvent being a substance with a boiling point below 150° C. that can dissolve polyisobutene, for example o-xylene) by combination of the components, comprising polyisobutene, polymer(s) Px, water, optionally surfactant, optionally oil and optionally further additives such as defoamers etc., and homogenization with a suitable device, like for example a high-shear mixer or for example a high-pressure homogenizer, optionally at elevated temperatures.
The step of combining the components can vary: in one preferred embodiment, polymer(s) Px is dissolved in polyisobutene, optionally comprising oil(s) and/or additional components, and then combined with the water phase, comprising water, optionally surfactant and additional components.
In another preferred embodiment, polymer(s) Px is dissolved in the water phase, comprising water, optionally surfactant and/or additional components, and then combined with polyisobutene phase, comprising polyisobutene and optionally oil(s) and/or additional components.
In another preferred embodiment of the invention, the preparation of the emulsion is achieved via a solvent route. The solvent route is especially suitable to prepare emulsions with anionic polymer(s) Px. The components of the emulsion, comprising polyisobutene and polymer(s) Px, are dissolved in a solvent, for example o-xylene, in a stirred reactor, optionally at elevated temperatures. After complete dissolution, water is added to the solution and the mixture is distilled, optionally under addition of water steam, at elevated temperature (above 80° C.) until the solvent is removed.
The use of an emulsion as described above in chemical technical applications, cosmetics, plant protection, preparation and treatment of paper, textiles and leather, adhesives, dye and pigment formulations, coatings, pharmaceutical applications, construction, wood treatment forms another aspect of the present invention.

After the temperature had reached 110° C., 184 g liquid maleic anhydride (melt of approx. 70° C.) were fed into the reaction over 5 hours and 5.5 g tert.-butyl peroctoate, dissolved in 25 g diisobutene (mixture of 2,4,4-trimethyl-1-pentene and 2,4,4-trimethyl-2-pentene) were fed into the reaction over 5.5 hours. The resulting terpolymer is A1.
Preparation of Terpolymer (A2):
The reaction mixture of Example 1 was cooled to 90° C. and 2400 g of water and 140 g aqueous NaOH (50 wt. %) were added at the same time. The mixture was subsequently stirred for 4 hours at 90° C. and then cooled to room temperature. The resulting terpolymer (A2) was received in the form of an aqueous dispersion of pH 6.5, having a water content of 80 wt % and a K-value of 14.7.
Preparation of Terpolymer (A3):
In a stirred vessel, 2350 g o-xylene, 1450 g maleic acid anhydride, 64 g polyvinyl ethyl ether (30.00% solution in o-xylene, BASF SE, Ludwigshafen, Germany) and 1470 g polyisobutene (molecular weight 1000 g/mol) were precharged. The vessel was set under nitrogen atmosphere and the pressure was set to approx. 300 mbar. Subsequently, the temperature was set to 110° C. and the pressure was maintained at 300 mbar. Within 5.5 hours, 62.5 g tert.-butylperoctoate in 625 g o-xylene were added to the reaction mixture. 5 min after start of the feed, a second feed of 649 g isobutene was started and dosed within 5 hours. The pressure of the reaction did not exceed 1.5 bar. After the end of the feed, the reaction mixture was stirred for one hour at 110° C. The resulting polymer A3 has a solids content of 51.3% and a K-value of 19.5 (1% in cyclohexanone).
Modification of Terpolymer A1 (A4).
To the obtained polymer solution (of A1) in o-xylene 5.2 g of dimethylaminopropylamine in o-xylene (250 ml) were added under stirring at 90° C. over 30 min. After stirring for further 30 min the resulting polymer solution was heated to 150° C. and kept at that temperature for 4 hours. Afterwards the temperature was lowered to 30° C. and a sufficient amount of o-xylene was added to maintain an acceptable viscosity. Then dimethylsulfate (3 g in 15 ml o-xylene) was added over 30 min to the stirred polymer solution. After 30 min at 20° C. the temperature was raised to 90° C. and kept for 1 hour. 500 ml of hot water were added and a water vapor distillation was carried out until all o-xylene had been removed. This resulted in terpolymer A4.

500 g of terpolymer A5 were placed in a 2 l stirred vessel and cooled to 10° C. 4.3 g of dimethylsulfate were added over 30 min. The temperature was kept below 30° C. After the addition was complete the polymer solution was stirred for 30 min at room temperature before the temperature was raised to 80° C. The o-xylene was removed in vacuum and the resulting polymer was grinded into a powder. This resulting powder was dissolved in 862 g of deionised water and 48.6 g 50%ic sodium hydroxide solution, yielding terpolymer A6.
Preparation of Terpolymer A7:
In a 2 l stirred vessel 663 g o-xylene and 240 g of powdered MSA/Cu-polymer were charged and heated to 90° C. 87 g dimethylaminopropylamine were dissolved in 100 g o-xylene and were added over 2 h at 90° C. Then the temperature was raised to 100 ° C. and kept there for 1 h. Then the temperature was raised to 150° C. and the water was distilled of using a Dean Stark condenser. This yielded a 28.5%ic solution of terpolymer A7.
Instead of dimethylaminopropylamine, also other amines such as aminopropylimidazole can be used.
