A novel catalyst system for the polymerization of alpha-olefins is provided. The catalyst system comprises:
(a) an organoaluminum containing component, e.g. triethyl aluminum, and
(b) a titanium halide containing component.
The titanium halide containing component is obtained by reacting a halogen containing magnesium compound, e.g. MgCl2, with an organic phosphite, e.g. triphenyl phosphite, to produce a reaction product. The reaction product is then co-pulverized with a complex of a titanium halide compound and an electron donor compound, e.g. TiCl4 ethyl benzoate, to produce a co-pulverized product. The co-pulverized product is then reacted with a titanium halide compound, e.g. TiCI4.
A novel titanium halide containing component is provided as well as a process for producing said component. A process for the polymerization of alpha-olefins is also provided.
提供了一种用于α-烯烃聚合的新型催化剂体系。该催化剂系统包括
(a) 含有机铝成分,例如三乙基铝,以及
(b) 一种含卤化钛的组分。
卤化钛成分是通过含卤素的镁化合物(如 MgCl2)与有机亚磷酸酯(如亚磷酸三苯酯)反应生成反应产物而得到的。然后将反应产物与卤化钛化合物和电子供体化合物(如 TiCl4 苯甲酸乙酯)的络合物进行共粉碎,生成共粉碎产物。然后再将共粉碎产物与卤化钛化合物(如 TiCI4)反应。
本发明提供了一种新型含卤化钛成分以及生产该成分的工艺。此外,还提供了一种α-烯烃聚合工艺。
