活性自由基聚合法制备以C60封端的聚苯乙烯

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，Ｃ６

Preparation of C60-end-Capped Polystyrene with Living Free Radical Polymerization

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 experimental results proved that this reaction was a typical living free radical polymerization. The C 60 -end-capped polystyrene was synthesized by the reaction of TEMPOL-end-capped polystyrene with C 60 . The experimental results of UV-Vis and GPC show that C 60 is chemically bonded to the polystyrene chain, and GPC results imply that all C 60 is monosubstituted, i.e. the polymer is C 60 -end-capped polystyrene.
