A novel process for producing homopolymers and interpolymers of olefins which involves contacting an olefin and/or an olefin and at least one or more other olefin(s) under polymerization conditions with at least one Ziegler-Natta catalyst comprising a component comprising at least one transition metal and a co-catalyst comprising at least one organometallic compound and at least one compound comprising at least one carbon-oxygen-carbon linkage (C—O—C) of the formula R1—O(—R2—O)m—R3 in amounts sufficient to reduce the electrostatic charge in the polymerization medium. Also disclosed is a process for reducing electrostatic charge in an olefin polymerization medium.
一种生产烯烃同聚物和交联聚合物的新工艺,涉及在聚合条件下将烯烃和/或至少一种其他烯烃与至少一种齐格勒-纳塔催化剂接触,该催化剂包括至少一种过渡金属组分和至少一种含有至少一个碳-氧-碳键(C-O-C)的化合物的协同催化剂,其化学式为R1-O(-R2-O)m-R3,其用量足以减少聚合介质中的静电荷。还公开了一种减少烯烃聚合介质中静电荷的工艺。
