| 摘 要： | 引言高抗冲聚苯乙烯(HIPS)可通过顺丁橡胶(PB)接枝苯乙烯共聚制备,相比通用聚苯乙烯(GPPS),其抗冲性能高、拉伸形变大,但这些性能受HIPS分子量及分布、接枝效率、橡胶粒子形态及大小的影响很大。制备时可改变剪切速率、橡胶类型及用量、引发剂用量来调节产物分子量及分布、接枝效率、橡胶粒子形态及大小,进而控制

| Abstract: | The synthesis of high impact polystyrene(HIPS)with the usage of a tetrafunctional peroxide initiator was investigated.The polymerization performance of a commercial initiator polyether poly-t-butylperoxy carbonate(JWEB50)was compared with that of its monofunctional counterpart,tert-butyl(2-ethylhexyl)monoperoxycarbonate(TBEC).It was shown that the polymerization kinetic curves completely overlapped at the same polymerization temperature when the molar concentrations of were equal for these two initiators.An... |
