摘要: 通过活性自由基聚合的方法制备了以2,2,6,6-四甲基-4-羟基呱啶氮氧自由基(TEMPOL)封端的聚苯乙烯大分子,实验结果证明该反应体系是一个典型的活性自由基聚合体系,同时研究了TEMPOL/AIBN的比例及AIBN的含量对聚合反应的影响。用以TEMPOL封端的聚苯乙烯和C60反应,制得了C60的聚苯乙烯高分子衍生物,紫外和GPC结果均证明C60已连接到聚苯乙烯的长链上,GPC的结果还证明,C6Abstract: A series of TEMPOL(2,2,6,6-tetramethyl-4-hydropiperdine-1-oxyl)-end-capped polystyrene were prepared with controlled living free radical polymerization. The influences of TEMPOL/AIBN ratio and the AIBN content on the polymerization were also studied, the
