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-C8 under action of catalyst promoter such as alkyl aluminium, alkyl aluminoxane, and so on.
含有杂原子的有机化合物及其在制备具有单活化中心的齐格勒-纳塔(Z-N)催化剂中的应用。Z-N 烯烃聚合催化剂的制备方法是在镁化合物/四氢呋喃溶液中加入经加热预活化或化学预处理的有机或无机固体载体或它们的化合物、含杂原子的有机化合物和金属化合物。本发明制备的 Z-N 烯烃聚合催化剂为可流动粉末,在烷基铝、烷基铝氧烷等催化剂促进剂的作用下,与 C3-C8 α-烯烃进行均聚和联合聚合时,可制备结构可控、催化活性高的乙烯均聚物和共聚物。
