Abstract
Process for the synthesis of polymers protected against the action of ultraviolet rays, by ligation of alkenyl groups, characterized by reacting, with the aid of polymerization catalysts, 0.1 to 100%, at least, of a compound of the formula ** (See formula) ** where U1 and U2 mean a hydrogen atom, a chlorine atom or a methyl group, V1 and V2 mean a hydrogen atom or a methyl group and D means a low molecular weight alkenyl group, and 99.9 to 0% at least, of another compound capable of reacting with the alkenyl groups.
