The invention relates to the free radical polymerization of tetrahalogen xylylene diacrylates monomers, either in a mixture of water-miscible aprotic solvent and water, or in a water-immiscible solvent, in the presence of a chain length modifier.
Compounds of the formula: ##STR1## WHEREIN: EACH X is chloro or bromo Y is methyl or bromo n is 0 or 1 Each of R and R' is hydrogen or methyl. The compounds are produced by contacting an alkali salt of R'--(CH.dbd.C(R)--COOH with tetrahalogen xylene chloride or xylylene dichloride or pentabromobenzylchloride in a polar solvent. The compounds are useful as comonomers and as cross linking agents in polymerization of unsaturated compounds.
