将商品氯化聚丙烯还原后作为原子转移自由基聚合的引发剂,在溴化铜/2,2′-联吡啶的催化下与聚苯乙烯接枝共聚。核磁共振氢谱分析结果表明聚丙烯与聚苯乙烯发生了接枝共聚;接枝率随聚合时间的增加而增大。
After chlorinated polypropylene was reduced, it was used as initiator of atom transfer radical polymerization. It was graft copolymerized with polystyrene under catalysis of cupric bromide / 2,2’-bipyridine. The results of 1H NMR showed that the graft copolymerization of polypropylene and polystyrene occurred. The graft ratio increased with the increase of polymerization time.
