摘要
以商品级的聚苯乙烯为原料,工业级二氯甲烷为溶剂,三氯化铝为催化剂,采用直接溴化法合成了线型高分子量的阻燃剂——溴代聚苯乙烯。其溴的含量是58％～61％,产率为86％～91％。
The linear high molecular weight Brominated polystyrene is prepared bydirect bromination by dissolving commericial grade polystyrene in industrialgrade dichloromethane and aluminium chloride as catalyst. Bromine contentsof products are 58%～61%. The yields are 86%～91%. The product can beas used flame retardant of high polymeric compounds.
