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.
