无规支化聚苯乙烯模型化合物的合成及表征

SYNTHESIS AND CHARACTERIZATION OF RANDOMLY BRANCHED POLYST YRENE MODEL COMPOUNDS

本文首次用两次偶合接枝的方法制备了不但在主链上有支链，而且在支链上也有支链的结构明确的无规支化聚苯乙烯模型化合物，并对所制备的１５个试样用ＣＰＣ－粘度计联用装置进行了表征。

Randomly branched polystyrene model compounds of known structure,which have branchedchain not only at its backbone chain but also at their branched chain are prepared for the firsttime,by coupling graft method in twice,Fifteen samplca thus obtained are characterized bymeans of the apparatus of GPC combined with a viscometer.
