The present disclosure provides metallocene catalysts for use in polymerization processes. Such catalysts may be used to generate polymers with low branching and high molecular weights. Also, the present disclosure provides methods of bimodal polymerization resulting in a duality of average molecular weight polymers being simultaneously produced. In the system, the size of the polymers produced can be controlled by modifying the type and amount of catalyst activator.
本公开提供了用于聚合过程中的茂
金属催化剂。这些催化剂可用于生成支链少、分子量高的聚合物。此外,本公开提供了双峰聚合的方法,导致同时产生两种平均分子量聚合物。在该系统中,通过修改催化剂活化剂的类型和数量,可以控制所产生聚合物的大小。
