HOMOGENEOUS METALLOCENE CATALYST FOR POLYMERIZATION OF OLEFINS ──Ⅰ. Study on Homopolymerization of Ethylene and Propylene
【摘要】 设计正交实验研究均相金属茂催化剂Cp2ZrCl2/MAO、Cp2TiCl2/MAO和Et(Ind)2ZrCl2/MAO催化乙烯和丙烯均聚时的聚合条件,如聚合温度、催化剂浓度、反应时间等,对聚合反应及聚合物性能的影响。对聚合反应机理进行了讨论。
【Abstract】 Studies on polymerization conditions of polymerization of ethylene and propylene with homogeneousmetallocene catalysts, Cp2ZrCl2/MAO, Cp2TiCl2/AO and Et (Ind)2 ZrCl2/MAO, were conducted on the experiments of orthogonal design. The effects of polymerization temperature and time as well as the concentration of the catalyst on polymerization reactions and the polymer properties were discussed.
