High stereoregularity, highly active catalytic performance, and good hydrogen response can be obtained by homopolymerizing propylene in the presence of a catalyst that includes a solid catalyst component including titanium, magnesium, a halogen, a carbonate compound represented by the following formula, and a diether compound. Excellent polymerization behavior can also be obtained when effecting random copolymerization or block copolymerization.
R1-O-C(=O)-O-Z-O-R2 (1)
wherein R1 and R2 are a hydrocarbon group or a substituted hydrocarbon group having 1 to 24 carbon atoms, or a heteroatom-containing group, provided that R1 and R2 are either identical or different, and Z is a linking group that links two oxygen atoms through a carbon atom or a carbon chain.
在催化剂(包括钛、镁、卤素、由下式表示的碳酸盐化合物和二醚化合物组成的固体催化剂组分)存在下均聚丙烯,可获得高立体规整度、高活性催化性能和良好的氢响应。在进行无规共聚或嵌段共聚时,也可获得优异的聚合性能。
r1-o-c(=o)-o-z-o-r2 (1)
其中,R1 和 R2 是具有 1 至 24 个碳原子的烃基或取代烃基,或含杂原子的基团,但 R1 和 R2 可以相同或不同;Z 是通过碳原子或碳链连接两个氧原子的连接基团。
