摘要：

Ethylene, propylene, and ethylidene norbornene (D) were terpolymerized by Et[Ind]2ZrCl2/MAO in solution and supported on silica. The presence of D decreases the rate of polymerization. EPDM containing between 3 and 22 wt % of D were synthesized which have narrow MW distribution. The supported catalyst produces EPDM with E/P ratio which are similar to the ratio in the feed.
