Abstract
Resin compositions, soluble in odorless mineral spirits, and dryable at room temperature after application to textiles, leather, wood or other surfaces to form soil-oil and water-repellent coatings. The resin compositions are terpolymers comprising a fluoroaliphatic vinyl monomer, a hydrocarbyl higher alkyl vinyl monomer and a polyfunctional vinyl monomer selected from the group consisting of (a) a vinyl amido glycolate ether monomer; (b) a monomeric vinyl diketo ester monomer and (c) a vinyl ester monomer containing hydroxy and halide groups.
Claims9
A hydrocarbon-soluble fluorinated terpolymer comprising the polymerization product of monomers comprising:
- (a) a fluorinated vinyl monomer containing at least one perfluoroaliphatic radical terminating in a CF3 group and containing at least 25 percent by weight of its fluorine in the form of fluoroapliphatic radical;
- (b) a higher aliphatic hydrocarbyl vinyl monomer containing a higher aliphatic hydrocarbyl group having from 8 to 20 carbon atoms, and
- (c) a polyfunctional vinyl monomer selected from the group consisting of (1) a vinyl amido glycolate ether (2) a vinyl diketo ester and (3) a vinyl ester compound having the formula:
- ##STR4## wherein R.sub.1 is hydrogen or a lower alkyl group having 1 to 4 carbon atoms, preferably hydrogen, X is a halogen atom, preferably chlorine, and R is H or CH.sub.3,
- said polymerization product being sufficiently soluble in odorless mineral spirits solvent for the application of odorless mineral spirit solutions containing effective amounts thereof to a variety of materials to substantially improve the oil-and water-resistance of such materials upon curing of said terpolymer.
