Copolymerization of Propylene and Ethylene over a Ti Cl_4/Al_3Cl_3/Hy-Zeolite Catalyst System

摘要

Using Y-zeolite as starting materials of supports, new supported catalysts for copolymerization of ethylene and propylene were prepared and their possible strutures were discussed. It was found the higher polymerization productivity, for instance, 10kgP/Gn.h can be obtained using TiCl_4/Al_2Et_3Cl_3/HY catalystic system and addition of MgClPh to this catalytic system can increase significantly the polymerization productivity
