    摘要: A 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 a Ziegler-Natta catalyst and dinitrogen monoxide in an amount sufficient to reduce the electrostatic charge in the polymerization medium. Also provided is a process for reducing electrostatic charge in the polymerization of an olefin by adding dinitrogen monoxide.

    摘要: There is described a process utilizing metallocene catalyst for producing ethylene/olefin interpolymers which, for a given melt index and density, have a reduced melting peak temperature (Tm). The process involves contacting ethylene and at least one other olefin under polymerization conditions with a metallocene catalyst and at least one modifier comprising at least one element from Group 15 and/or Group 16 in amounts sufficient to reduce the melting peak temperature of the ethylene/olefin interpolymer. Also described herein are ethylene/olefin interpolymers resulting from the process.
