In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.

本文利用三氯化铝作催化剂,废聚与溴发生亲电取代反应成溴化聚阻燃剂。

The title resin has been prepared by Friedel-Crafts acylation followed by bromination and amination.The method avoids the utilization of cancerogenic chloromethyl methyl ether.

氏酰基化反应引入酰基，接着溴化、胺化，得到标题树脂。该法避免了使用氯甲醚。
