In certain embodiments, the compositions comprise from about 0.1 to about 50 percent, by weight of the entire composition, of a polymer according to the present invention. In certain preferred embodiments, from about 2 to about 50 weight percent of polymer of the present invention.
- leveling aids such as , butyl carbitol, trimethylpentane diol monoiso
- compositions of the present invention are used in methods for treating a substrate comprising applying a composition of the present invention onto a substrate and drying/curing said composition on said substrate.
- Any of a wide range of methods for applying the present composition onto a substrate may be used according to the present invention. Suitable methods include, for example, padding, foaming, spraying and the like.
- the composition is dried or cured by exposing the composition to heat.
- the composition may be cured using any suitable heat source. While the preferred embodiment involves heat-curing the curable composition, one skilled in the art will appreciate that many variations of the method within the scope of the claims is possible depending on the nature of the curable composition. For example, if desired, the curing of the curable composition may be accelerated using microwave treatment procedures known in the art.
- the present invention also provides for a coating or film formed by curing a curable composition of the present invention.
- HFP refers to both the saturated and unsaturated groups derived from hexfluoropropene, i.e., -
- the acrylate of 2,2,3,4,4,4-hexafluorobutanol was obtained from the Aldrich Chemical Company.
- the acrylate (9.9 g), 0.10 g sodium persulfate, 0.40 g sodium dodecyl sulfate, and 30 mL water were combined and purged with nitrogen to remove oxygen from the system.
- the mixture was then heated to 50 "C with good stirring in a nitrogen atmosphere for 6 hours.
- a homopolymer latex was obtained.
- CH 2 CHCO 2 CH(CH 2 OCH 2 CF 2 CFHCF 3 ) 2 (6.0 g), AIBN (0.060g), heptane (20mL) and ethyl acetate (20mL) were combined. The stirred solution was purged withN 2 and heated to 50 °C for 20 h. A transparent polymer solution was obtained.
- Hexafluorobutyl acrylate (8.0 g) and 0.80 g AIBN were dissolved in 20 mL each of ethyl acetate and heptane. After purging nitrogen through the solution to remove oxygen, the solution was heated to 50 °C for 15 hours.
- This example illustrates the low surface energy of polymers of the present invention.
- Thin films of polymers on glass slides were prepared by placing a solution of the polymer on the slide. After about 10 seconds, the solution was drained off the slide. The slide was then dried in an oven prior to making contact angle measurements with a goniometer. Oil repellency tests were also performed according to AATCC test method 118-1997. This test measures the rate at which hydrocarbon oils of different molecular weight spread on a filter paper that has been treated with the test polymer. A higher numerical grade indicates more resistance to the spreading of hydrocarbon fluids.
- the oil used in the contact angle measurements is light mineral oil. The resulting data is shown in Table 1.
- Compound A is the acrylate of (CF 3 CHFCF 2 CH 2 OCH 2 ) 2 CHOH;
- Compound B is
- CH 2 CHCONHC(CH 2 OHFP) 3 ;
