POLYMERIZABLE COMPOUNDS WITH ONE OR MORE SURFACTANT-LIKE PROPERTIES

TECHNICAL FIELD

The present disclosure relates to the field of biocidal compounds and precursors thereof. In particular, the present disclosure relates to biocidal compounds, and precursors thereof, that have surfactant-like properties.

BACKGROUND

Microbial resistance to biocidal compounds poses a large and growing threat to human health. Various circumstances and applications call for the use of biocidal compounds. Currently, there are different broad-spectrum biocidal compounds that are employed extensively during disinfection applications, including: silver, hydrogen peroxide, nitrogen oxide, sodium hypochlorite, quaternary ammonium compounds (QAC) and N-halamine compounds.

It is known to incorporate biocidal compounds into polymer coatings for hard and soft surfaces in an effort to provide a polymer coating with biocidal activity. Surfactants are also known to be used in the process for making polymer coatings, such as coatings that include latex-polymer particles. However, utilizing a surfactant compound in an emulsion polymerization process can have detrimental effects. These detrimental effects can be caused by weak hydrophobic interactions between the surfactant compound and latex-polymer particles within the emulsion, which can allow the physically-adsorbed surfactant compound to desorb from the surface of the latex-polymer particle. This desorption can destabilize the latex, which can be exacerbated under one or more of: exposure to high shear, freezing, high and low temperatures and exposure to high ionic-strength conditions. Furthermore, when the polymer latex is applied as a polymer-coating film, the physically-adsorbed surfactant compound can migrate toward the air-film or the substrate-film interface. During film formation, surfactant compounds that are strongly adsorbed may also be trapped at particle/particle boundaries, which can create hydrophilic pathways within the polymer-coating film. In some cases, the surfactant compound may be pushed away from the particle/particle boundaries, which can create small pockets or aggregates throughout the polymer-coating film. Such a heterogeneous distribution of the surfactant compound within the polymer-coating film may adversely affect the coating film's performance. For example, it is known that adhesion strength, shear strength, water resistance, gloss and film appearance can be adversely affected by any migration of the surfactant compounds within a polymer-coating film.

Surface Tension Measurements

Compounds of Formula 5, Formula 6 and Formula 9 were subjected to surface tension experiments to assess any surfactant-like properties.

A KRUSS K100 Tensiometer was used to determine the surface tension of a sample of the compounds in liquid water at different concentrations. The concentrations tested were 0.5%, 1.0%, 3.0%, 5.0% and 10%. A platinum plate with dimensions of about 19.9 mm×about 0.2 mm×about 10 mm (width, thickness and height respectfully) was attached to a sensitive mass balance. The sample was raised to the fixed platinum plate at a rate of 10 mm/min with a detection sensitivity of 0.005 g until the liquid sample reached the bottom of the plate. The plate was then immersed in the liquid sample at a depth of 2 mm for 60-150 seconds and any change in mass was recorded by the equipment as a function of time. Force was determined using the equation f=ma.

The surface tension (γ) of each liquid sample was calculated from the force measurement (f) using the equation outlined in Method C: Surface Tension by Wilhelmy plate, ASTM D1331-14.

$γ = \frac{f}{2 (l + t)} \cdot \cos θ$

where (l) is the length and (t) is the thickness of the plate. The contact angle was assumed to be 0. The test results describe a trend and general indication of the surfactant properties of each compound tested.

Each of the compounds tested demonstrated surfactant-like properties as evidenced by the surface tension values that were measured as compared to water which is about 72 mN/m.

Example 2—Coating Formulations

Each of the compounds with Formula 5-13 and Formula 18-20 were used to make a polymer coating formulation by a latex-emulsion polymerization process. All coating formulations included a mixture of n-butyl acrylate and methyl methacrylate as major constituents of the polymer backbone, with which each of the compounds of Formula 5-13 and Formula 18-20 were mixed and emulsified.

Briefly, water and a non-ionic surfactant were placed in a multi-neck glass reactor equipped with a water bath, condenser, nitrogen line, an overhead stirrer, and an anchor type agitator. The temperature was raised to about 70° C. before about 2% of a pre-emulsion of monomers was added. The pre-emulsion of monomers comprises a mixture of MMA and BA monomers, non-ionic surfactant and water. This mixture was emulsified by high speed agitation to form a stable “pre-emulsion”. A cationic radical seed-2,2′-Azobis(2-methylpropionamidine)dihydrochloride added at 0.2 wt % in total was next added which immediately turned the dispersion blue, indicating the beginning of polymerization and formation of seed particles. Monomer emulsion and initiator feeding was then carried out over a period of about 3 hours, after which the temperature was raised to about 75 ° C. at which the latex emulsion was held for about 1 hour before cooling the latex down to about 50° C. Chasers were then added at 50° C., with tert-butyl hydrogen peroxide at 0.1 wt % added as a shot and mixed-in for 15 minutes, while BRUGGOLITE® FF6M (BRUGGOLITE is a registered trademark of L. BRUGGEMANN KG) at 0.1 wt % was fed-in gradually over 30 minutes. When the chasers were added the latex was cooled down to about 30° C. and an oil-based antifoam agent (Rhodoline 646) at 0.2 wt % was added before filtering the latex through a 150 μm filter. Final pH was recorded. Level of coagulum for all coating formulations was less than 0.1%.

Biocidal Activity Testing

Coating formulations were tested for biocidal activity in accordance with ISO 22196: Measurement of antibacterial activity on plastics and other non-porous surfaces. Briefly, the sample size was scaled down to 2.5 cm×2.5 cm and the test conditions included testing in phosphate buffered saline (PBS) or 5% fetal bovine serum (FBS). The samples were challenged with E. coli (ATCC 25922). An overnight culture of E. coli was diluted to 106 colony forming units (CFU)/mL, and about 50 μL of the diluted bacterial was added onto a 2.5 cm×2.5 cm testing surface that was coated with one of the coating formulations. Per ISO 22196 protocol, a polyethylene terephthalate cover film (2 cm×2 cm) was applied overtop to ensure contact between the coating formulation and the bacteria. The test surfaces then incubated with the bacteria at room temperature for the reported contact times. At the end of each contact time 2.5 ml of neutralizer was added to allow counting of bacteria.

Table 11 summarizes the biocidal activity experimental data of F1 variants of the coating formulations with or without exposure to 200 ppm of chlorine for 10 minutes at a pH of 10.7 following exposure to E. coli in PBS.

Without being bound by any particular theory, it is postulated that unchlorinated killing of microbes was due to the use of the cationic surfactant (C-TAB) in the latex synthesis steps, as shown in Table 6.

Protein Adsorption Testing

Various of the coating formulations were tested for the relative protein adsorption into the surface of the coating formulations. These tests are based upon a Lowry/BCA assay kit to measure the concentration of eluted protein from the surface of the coating formulations. Table 17 summarizes the protein adsorption data obtained by these experiments using 5% FBS and E. coli exposure as described herein above.

Biocidal Activity Testing

Coating formulations were tested for biocidal activity in accordance with ISO 22196: Measurement of antibacterial activity on plastics and other non-porous surfaces. Briefly, the sample size was scaled down to 2.5 cm×2.5 cm and the test conditions included testing in PBS or 5% FBS. The samples were challenged with E. coli 0157. An overnight culture of E. coli was diluted to 106 colony forming units (CFU)/mL, and about 50 μL of the diluted bacterial was added onto a 2.5 cm×2.5 cm testing surface that was coated with one of the coating formulations. Per ISO 22196 protocol, a polyethylene terephthalate cover film (2 cm×2 cm) was applied overtop to ensure contact between the coating formulation and the bacteria. The test surfaces then incubated with the bacteria at room temperature for reported contact times. At the end of each contact time 2.5 ml of neutralizer was added to allow counting of bacteria.

Table 23 summarizes the biocidal activity experimental data of F1 variants of the coating formulations tested with or without exposure to 200 ppm of chlorine for 10 minutes at a pH of 7 following exposure to E. coli in 5% FBS.

Humidity and UV Resistance Testing

FIG. 25 through to FIG. 33 summarize the results of humidity-resistance tests of polyurethane coating formulations made according to embodiments of the present disclosure. The humidity-resistance tests were conducted in accordance with ASTM D2247 and D870: in 100% relative humidity.

FIG. 34 through to FIG. 42 summarize the results of ultraviolet resistance tests results of polyurethane coating formulations made according to embodiments of the present disclosure. The ultraviolet resistance tests were conducted according to ASTM D4587 Standard Practice for Fluorescent UV/Condensation cycles: 4 hours of exposure to ultraviolet radiation (340 nm, 0.89 W/(m2·nm) followed by about 4 hours of condensation at about 60° C.

FIG. 43 shows a first vial 10 and a second vial 12. The first vial 10 contains a volume of fluid latex emulsion that does not contain a polmerizable compound with surfactant-like properties (F3-control). The second vial 12 contains a polmerizable compound with surfactant-like properties (F4-M6-6% as shown in Table 5 and Table 9). The two vials 10, 12 were kept closed at room temperature for about ten months. the first vial 10 clearly shows the growth of microbes and the second vial 12 does not.
