Abstract
Copolymers of certain amounts of ethylene, carbon monoxide, a third monomer copolymerizable therewith to provide solid but flexible polymers, and a fourth monomer containing epoxy side groups provide new and useful copolymers. The copolymers are useful as blending resins with thermosetting resins. Blends of these copolymers with thermosetting resins provide performance unattainable with the thermosetting resin alone in terms of flexibility, toughness, and adhesion. Such blends may be used, for example, to produce flexible, semirigid or rigid films, coatings, fibers, foams or molded articles.
Claims30
A solid ethylene - carbon monoxide copolymer containing epoxy side groups, said copolymer consisting essentially of, by weight (a) 40 to 90 percent ethylene;
- (b) 2 to 20 percent carbon monoxide;
- (c) 5 to 40 percent of a monomer copolymerizable therewith to provide flexible polymers, said monomer taken from the class consisting of unsaturated mono- or dicarboxylic acids of 3 to 20 carbon atoms, esters of said unsaturated mono- or dicarboxylic acids, vinyl esters of saturated carboxylic acids where the acid group has 1 to 18 carbon atoms, vinyl alkyl ethers where the alkyl group has 1 to 18 carbon atoms, acrylonitrile, methacrylonitrile, alpha-olefins of 3 to 20 carbon atoms, norbornene, and vinyl aromatic compounds;
- and (d) 0.1 to 5.0 percent of an ethylenically unsaturated monomer of 4 to 21 carbon atoms containing an epoxy group.
