摘要： Processes of polymerizing olefins. The process includes polymerizing contacting ethylene and a (C3-C40)alpha-olefin comonomer in the presence of a catalyst system comprising a procatalyst and a bimetallic activator complex. The bimetallic activator complex includes an anion and a countercation. The anion having a structure according to formula (I).

摘要： The present disclosure relates to an olefin polymerization catalyst system for use in forming a multi-block copolymer, said copolymer containing therein two or more segments or blocks differing in chemical or physical properties, a polymerization process using the same, and the resulting polymers, wherein the composition comprises the admixture or reaction product resulting from combining: (A) a first olefin polymerization procatalyst, (B) a second olefin polymerization procatalyst capable of preparing polymers differing in chemical or physical properties from the polymer prepared by procatalyst (A) under equivalent polymerization conditions, and (C) a chain shuttling agent.
