Allyl-acrylic monomers, their preparation and polymers derived therefrom

摘要

Novel allyl-acrylic monomers of the formula: <IMAGE> wherein R is a C1-4 alkylene group and R1 is hydrogen or methyl, are described. The preferred monomer is that in which R is ethylene and R1 is methyl. When subjected to conventional free radical polymerization, in one stage or two stages, these monomers give transparent polymers having good mechanical properties, particularly hardness.
