摘要

分子筛是由TO4（T ＝ Al，Si 或P，少数情况下是B，Ga，Be 等其它原子）四面体之间通过共享顶点而形成的三维四连接骨架。烯烃配位聚合反应是一类重要的高分子化学反应，将烯烃配位聚合催化剂负载于不同结构与孔径的分子筛后，分子筛不仅能起载体的作用，调变聚合反应的动力学行为，改善聚烯烃的形态；其纳米孔道更是烯烃聚合的反应器，可以调节所得聚烯烃的分子量及其分布、加工流变性能、立构规整性和共聚物中共单体的含量。本文着重论述了分子筛负载催化剂的烯烃配位聚合反应新进展。

Abstract

Zeolites are crystalline aluminosilicates with a framework structure based on the three-dimensional arrangement of TO4 (T = Al

etc) . Molecular sieves play both the role of supports of catalysts and nanoreactor for the olefin polymerization to proceed. The olefin polymerization process is more controllable due to the immobilization and the resulting polyolefin exhibits adjustable molecular weights
