摘要: 星形聚合物可以作为研究高聚物支化效应的模型化合物。这方面工作已有报导。但是以多官能度的氯硅烷为偶联剂合成等臂长不同支化度的系列星形聚苯乙烯模型化合物的工作尚未见报导。本文报导了多官能度偶联剂和3、4、6、8、12臂的等臂长的系列星形聚苯乙烯样品的合成。

Abstract: Aseries of star polystyrenes having the same length of branch chain and different degree of branching 3, 4, 6, 8, and 12 have been synthesized with poly-functional chlorosilane as the linking agent through anionic oplymerization in the system of s-BuLi/bcnzcne. The results of synthesis were analyzed with GPCand Ubbelohde viscometer.
