A class of polymer precursor materials, which, under appropriate conditions, react to form cross-linked polymers, is disclosed. These materials contain a backbone segment, such as polyacrylate, having pendant therefrom mono- or disubstituted olefinic groups, such as vinyl itaconate, having specific polymerization rates. This class of materials, especially when coupled with specifically-defined oxygen-activated catalyst systems, provide paint and plastic compositions which exhibit excellent film formation, strength and durability characteristics.

A composition comprising an agent for preparing crosslinked polymers comprising: (a) a major portion of a polymer selected from the group consisting of polyacrylates and polymethacrylates having a molecular weight of from about 1,000 to about 10,000, this portion constituting the backbone of said agent; and (b) a minor portion of mono- or disubstituted olefinic groups pendant from said backbone, with the olefinic substituents on the groups being unpolymerized, said groups having polymerization rate constants of from about 10×10-4 to about 1000×10-4 mole-½liter½minute-1 at 70°C.; together with an amount of a catalyst sufficient to crosslink from about 2% to about 60% of the pendant groups of said agent within about 48 hours upon exposure to oxygen, heat, light or ultraviolet radiation.
