摘要
本文用阴离子聚合的聚苯乙烯进行氯甲基化,再将此带有活泼氯的甲基化聚苯乙烯作为主链与活性聚苯乙烯阴离子偶合接枝,制备了12个具有等长度支链沿主链无规分布的、结构明确的梳形聚苯乙烯模型化合物,并用GPC—粘度计联用装置对之进行了表征.
The polystyrene samples prepared by some anicus are chloromethylated. then twelve comb—shaped polystyrene model compounds of known structure, whose equal length branched chain is randomly distributed along the backbone chain, were prepared by the coupling graft reaction between living polystyrene anion and chloromethylated polystyrene as backbone chain. They are characterized by GPC in conjunction with viscometer.
