摘要

合成了组成为聚(4-乙烯基吡啶)-硅胶(SAV)的有机-无机复合载体茂锆催化剂

并用固体13C-NMR谱、元素分析(EA)、光电子能谱(XPS)等方法进行了表征.发现由SAV负载的茂锆催化剂可在相对较低的甲基铝氧烷(Al/Zr=600)用量下聚合乙烯.其活性(1.12×103kg PE/mol Zr.h)远高于SiO2负载的茂锆催化剂(0.22×103kg PE/mol Zr.h).

Abstract

Organic—inorganic hybrid(SAV)supported zirconocene was synthesized and its catalysis on ethylene polymerization was examined．The SAV was synthesized by eopolymerization of 4-vinylpyridine with vinyl silica monomer(SA)

which was modified by reacting silica with allyltrimethoxysilane(APS)．After treated by MAO．the SAV was reacted with Cp2ZrCl2 to form organic—inorganic hybrid supported metallocene．The chemical structure and the composition of SA and SAV have been characterized by sdid—state13C-NMR

XPS

and elemental analysis (EA)．The SAV supported zirconocene catalyst was effective in ethylene polymerization at a relatively low MAO level (A1／Zr=600)giving higher activity than that supported by SiO2．
