Abstract
Abstract New and useful polymers are prepared by reacting olefin-terminated prepolymeric materials with simple polyamine, by reacting simple olefins with amine-terminated prepolymers and by reacting olefin-terminated prepolymers with amine-terminated prepolymers. The new and useful polymeric materials so obtained can be cured as with heat, with or without catalyst, to provide products useful for preparing films, laminates, composites, prepregs, molding materials, varnishes, wire enamels and the like.
