A process for the polymerization of olefins, in particular a process for the copolymerization of propylene with further olefins, is carried out in the presence of highly active catalyst systems comprising specifically selected metallocenes, in particular ones which bear different substituents in position 2 and position 4 on an indenyl ligand. Novel polypropylene copolymers can be obtained by this process.
一种聚合烯烃的工艺,特别是
丙烯与其他烯烃的共聚工艺,是在高度活性催化剂系统的存在下进行的,该系统包括特别选择的
金属茂配合物,特别是那些在茂基
配体的2号和4号位置带有不同取代基的
金属茂配合物。通过这种工艺可以获得新型聚
丙烯共聚物。
