Abstract
Resin compositions, soluble in odorless mineral spirits, autooxidizable and air-dryable 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 hydroarbyl higher alkyl vinyl monomer and an acrylic or methacrylic ester of a compound having one or more unsaturated olefinic bonds, which latter ester imparts autoxidizability to the compositions.
Claims11
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 CF.sub.3 group and containing at least 25 percent by weight of its fluorine in the form of fluoroapliphatic radical;
- (b) an alkyl vinyl ester monomer where the alkyl group has 8 to 20 carbon atoms, and
- (c) an autoxidizable vinyl ester monomer which imparts autoxidizability to the terpolymer, selected from the group consisting of (1) a vinyl monomer having a pendant drying oil functionality and (2) a dicyclopentenyloxyalkylene vinyl ester and (3) a diclclopentenyloxy vinyl ester,
- 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 autoxidation curing of said terpolymer.
