Functionalized thermoplastics such as styrene-maleic anhydrate copolymers polystyrene or maleated polyolefins may be toughened with halogenated rubbers which are copolymers of isoprene and isobutylene provided a dialkyl or dihydroxyalkyl amino alkanol is present as a compatibilizer. The toughened thermoplastics have about a two fold increase in IZOD impact resistance.  
                            功能化热塑性塑料,如
苯乙烯-马来
水合共聚物聚
苯乙烯或
马来酸化聚烯烃,可以用卤化橡胶进行增韧,卤化橡胶是
异戊二烯和
异丁烯的共聚物,但必须有二烷基或二羟基烷基
氨基烷醇作为相容剂。增韧后的热塑性塑料的 IZOD 抗冲击性提高了约两倍。
