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。
Star polymers can be used as model compounds to study the branching effect of polymers. Work in this area has been reported. However, the synthesis of a series of star-shaped polystyrene model compounds with different arm lengths by using multifunctional chlorosilanes as the coupling agent has not been reported yet. This paper reports the synthesis of multifunctional coupling agents and a series of star-shaped polystyrene samples of 3, 4, 6, 8, and 12 arms.
