ORGANIC COMPOUNDS CONTAINING HETEROATOMS AND THEIR USE IN ZIEGLER-NATTA CATALYST WITH SINGLE ACTIVATION CENTER
摘要
Organic compounds containing heteroatoms and their use in preparing Ziegler-Natta (Z-N) catalyst with single activation center. The Z-N olefin polymerization catalyst is prepared by adding organic or inorganic solid carrier or compound of them which is pre-activated by heating or pre-treated chemically, organic compound containing heteroatoms and metallic compound into magnesium compound/tetrahydrofuran solution. The Z-N olefin polymerization catalyst prepared in the present invention is fluidizable powder and can prepare ethene homopolymer and copolymer of controllable construction with high catalytic activity, during homo-polymerization and combined polymerization with alpha-olefin of C3~C18 under action of catalyst promoter such as alkyl aluminum, alkyl aluminoxane and so on.
