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.
化合物的化学式为:##STR1## 其中:每个X是氯或溴,Y是甲基或溴,n为0或1,R和R'中的每一个都是氢或甲基。这些化合物是通过在极性溶剂中与R'-(CH.dbd.C(R)-COOH的碱盐接触四卤代二甲苯氯化物或二氯代二甲苯或五溴苯甲基氯化物而产生的。这些化合物在不饱和化合物聚合中作为共聚单体和交联剂是有用的。
