The present invention relates to compositions comprising an organic material, preferably a synthetic polymer, susceptible to oxidative, thermal or light-induced degradation and to esters, amides or urethanes of perfluorinated alcohols as reducer of surface energy of these materials, for example as oil and water repellency agents for organic materials.
The use of various fluorochemical compositions on fibers and fibrous substrates, such as for example textiles, carpets, paper, leather and non-woven webs to impart oil and water repellency is known for example in U.S. Pat. No. 6,127,485. This reference discloses hydrophobic and oleophobic fibers, films and molded articles comprising synthetic organic polymer wherein dispersed within the fiber, fabric or molded article and present at the surface of the fiber, fabric or molded article are fluorochemical compounds.
The known fluorochemicals do not satisfy in every respect the high requirements which a melt additive is required to meet as reducers of surface energy for organic materials, for example, for increasing the oil and water repellency of organic materials.
It has now been found that esters, amides or urethanes of perfluorinated alcohols are useful for various technical applications such as for example for increasing the oil and water repellency of organic materials like for example synthetic polymers.

The further additives are typically used in concentrations of 0.01 to 10%, based on the total weight of the material to be treated.
Preferred compositions of the invention comprise, as other additives phenolic antioxidants, light stabilizers and/or processing stabilizers.
Incorporation of component (b) and, if desired, further additives into the synthetic polymers is carried out by known methods, for example before or during moulding or else by applying the dissolved or dispersed compounds to the synthetic polymer, if appropriate with subsequent slow evaporation of the solvent.
The present invention also relates to a composition in the form of a masterbatch or concentrate comprising component (a) in an amount of from 5 to 90% and component (b) in an amount of from 5 to 80% by weight.
Component (b) and, if desired, further additives, can also be added before or during polymerisation or before crosslinking.
Component (b), with or without further additives, can be incorporated in pure form or encapsulated in waxes, oils or polymers into the synthetic polymer. Component (b), with or without further additives, can also be sprayed onto the synthetic polymer. It is able to dilute other additives (for example the conventional additives indicated above) or their melts so that they too can be sprayed together with these additives onto the polymer. Addition by spraying on during the deactivation of the polymerization catalysts is particularly advantageous, it being possible to carry out spraying using, for example, the steam used for deactivation.
In the case of spherically polymerized polyolefins it may, for example, be advantageous to apply component (b), with or without other additives, by spraying.
The synthetic polymers prepared in this way can be employed in a wide variety of forms, for example as foams, films, fibres, tapes, moulding compositions, as profiles or as binders for coating materials, especially powder coatings, adhesives, putties or especially as thick-layer polyolefin mouldings which are in long-term contact with extractive media, such as, for example, pipes for liquids or gases, films, fibres, geomembranes, tapes, profiles or tanks.
The preferred thick-layer polyolefin mouldings have a layer thickness of from 1 to 50 mm, in particular from 1 to 30 mm, for example from 2 to 10 mm.
The compositions according to the invention can be advantageously used for the preparation of various shaped articles. Examples are:

In order to determine the repellency properties of the compounds of the formula I, they are tested according to the following procedure. The sample preparation is a combination of polypropylene nonwovens and the additive and a thermal treatment (e.g. 130° C. for 10 minutes), which enables the migration of the additive to the surface and a proper surface rearrangement of the chemical groups. This extra heat cycle is needed to melt the compounds of the formula I in order to obtain a homogeneous redistribution over the surface of the substrate. An industrial sample of polypropylene nonwoven, fabric weight: 40 g/m2, is dipped into a 1% isopropanol solution of the test compound, simultaneously applying ultrasonic energy for one minute. After that, the sample is dried overnight at room temperature and then two hours at 90° C. in an oven. A part of the sample is afterwards annealed for 10 minutes at 130° C.
The treated nonwoven samples are evaluated in the water repellency test similar to INDA test method 80.8 (99). The wetting behavior of the nonwovens is tested with a series of water/isopropanol mixtures. The observation of the wetting behavior is rated from 0 (water wetting, no repellency) to 10 (optimum water repellency). The results are summarized in Table 1.
a)Comparative Example.
b)Example according to the invention.
The treated nonwoven samples are evaluated in the oil repellency test similar to AATCC test method 118-1997/ISO 14419. This test follows the same concepts of the already described for water repellency test method, but using, as test solvents, a series of hydrocarbons. The observation of the wetting behavior is rated from 0 (no repellency) to 8 (optimum repellency). The results are summarized in Table 2.

This liquid is added at 10-20 ml/min to a twin-screw extrusion of polypropylene pellets via a heated graduated cylinder using a Leistritz MIC 27/GL-32D twin-screw extruder. The extruder zones are 150°-195° C. with the main screw at 500 RPM and the PP feeder at 200-250 RPM. The molten polymer and additive exit via a two orifice round die. The molten material is immediately cooled and solidified in a cold-water trough. The solidified strand is fed into a Conair/Jetro 304 Pelletizer. The polypropylene used for the spunbond processing is PP 3155 from ExxonMobil (melt flow rate 36 g/10 min) and PP 3546 from ExxonMobil (melt flow rate 1200 g/10 min) for the meltblown processing.
Alternatively, the compound of formula 101 is made into masterbatches by those skilled in the technique. The masterbatch at the desired level is then tumble mixed with the appropriate polypropylene for making spunbond and meltblown nonwovens.
Tumble Mixing The concentrate pellets are let down with additional polypropylene pellets and are mixed with a Marion SPS 1224 mixer, resulting in a desired additive concentration by weight.
Spunbond Process Spunbond nonwoven polypropylene fibers are prepared from the tumble-mixed additive pellets prepared as above using a 1-meter wide Reicofil II Spunbond Pilot Line, under the following conditions: Extruder temperature of 200-220° C. Screen changer temperature of 205° C. Spin pump speed of 9 rpm. 4,000 Hole spinneret with a temperature gradient of 223-240° C. Bonder pressure of 260-300 PLI with bonding temperature of 130-140° C. Cooling air speed of 1700 rpm and suction air speed of 1500 rpm, and collection take up speed is adjusted to produce a nonwoven with a specific basis weight.
Meltblown Process Meltblown polypropylene fibers are also prepared from the tumble-mixed additives pellets prepared as above using 24-inch Reifenhauser Melt Blowing Pilot Line with Bi-component technology, under the following conditions: Extruder temperature of 160-240° C. for both A & B extruders. Screen changer temperature of 240° C. Spin pump speed of 16 rpm for both A & B extruders. Die temperature gradient of 240° C. Throughput 29.7 kg/h. Suction blower speed of 2000 rpm. Spin belt speed is adjusted to produce a nonwoven with a specific basis weight.
Alternatively: Meltblown polypropylene fibers are also prepared from the tumble-mixed additives pellets prepared as above using a custom-built 6-inch Melt Blowing Pilot Line under the following conditions: Extruder temperature of 175-265° C. Die temperature of 265° C. Throughput 0.49 g/h/m (4.44 kg/h). Spin drum speed is adjusted to produce a nonwoven with a specific basis weight.
The produced nonwoven samples are evaluated on their water/alcohol repellency behavior similar to INDA standards (International Nonwoven and Disposables Association). The results are summarized in Table 3.
