| 摘 要： | 大分子单体(macromer)共聚合为合成结构确定的接枝共聚物提供了新途径,但用络合催化剂进行共聚的例子很少。前文报导了末端为降冰片烯(NB)的聚苯乙烯大分子单体PS-NB的合成及表征;现报告其与乙烯的共聚,以制备主干为聚乙烯(PE)、支链为聚苯乙烯(PS)的接枝共聚物PE-g-PS的初步结果。

| Abstract: | Graft copolymers with polyethylene (PE) backbone and polystyrene (PS) grafts were prepared by copolymerization of norbornene-capped polystytene macromer (PS-NB) with ethylene using Ziegler-Natta catalysts. Purified products were characterized by GPC and IR.The relatively low conversion of PS-NB was attributed to micro-phase separation in the copolymerization. The graft copolymers exhibited mechanical properties similar to those of PE obtained with tbe same catalyst system. |
