COPOLYMERS FROM BIFUNCTIONAL VINYL AND AL LYL MONOMERS

The copolymerization behaviour and the formation of networks of comono mers with two olefinic double bounds were tested by free radical copol ymerization in solution. The products were characterised by investigat ion of the molecular weight and the thermal behaviour. The copolymers of vinyl and allyl methacrylate, acrylate and crotonate were considere d in comparison with methyl methacrylate, N-cyclohexyl maleimide and N -phenyl maleimide. The network of the polymers with C-C double bonds i n the side chain depends on the type of the copolymer and the concentr ation of the reactive groups. Crotonates polymerized with the vinyl or allyl group, in contrast to the analogous acrylates and methacrylates .
