Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
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 abd (2) a vinyl diketo ester and (3) a vinyl containing hydroxy and halogen groups, said polymerization product being sufficiently soluble in odorless mineral spirits solvent for the application of odorless mineral spiril solutions containing effective amounts thereof to a variety of materials, such as textiles, to substantially improve the oil-and water-resistance of such materials upon curing of said terpolymer.
Claim 2
Dependent Claim
142 words
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 abd (2) a vinyl diketo ester and (3) a vinyl containing hydroxy and halogen groups, said polymerization product being sufficiently soluble in odorless mineral spirits solvent for the application of odorless mineral spiril solutions containing effective amounts thereof to a variety of materials, such as textiles, to substantially improve the oil-and water-resistance of such materials upon curing of said terpolymer.
