摘要
研究了不同的茂钛催化剂与甲基铝氧烷(MAO)组成的催化体系对乙烯的聚合,发现钛的配体会大大影响聚合活性。从聚乙烯的透射电镜照片及偏光显微镜的照片,进一步证实聚乙烯的结晶性很好,且结晶度随结晶条件而变化。
Abstract
The polymerization of ethylene with varioustitanocene/methylaluminoxane (MAO) catalytic systems was studied. Results showed that the ligand of titanium affects the catalytic activity seriously. Crystallinity of polyethene as shown by spherulite observation of TEM and PM microroph was very good.
