Class of organic compounds containing heteroatom and its applications in preparing single-site ziegler-natta catalyst |
| abstract |
Organic compounds containing heteroatoms and their use in preparing Ziegler-Natta(Ziegler-Natta) catalyst with single activation center. The Ziegler-Natta olefin polymerization catalyst is preparing 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 Ziegler-Natta 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 C 3 ˜C 18 under action of catalyst promoter such as alkyl aluminum, alkyl aluminoxane, and so on. |
