Abstract
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 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.
Claims42
A process for polymerizing an olefin and/or an olefin and at least one or more other olefin(s) comprising contacting, under polymerization conditions, in a polymerization medium wherein electrostatic charge is present, the olefin and/or an olefin and at least one or more other olefin(s) 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 dinitrogen monoxide (N2O), wherein the dinitrogen monoxide is present in an amount sufficient to reduce electrostatic charge in the polymerization medium to a level lower than would be obtained in the absence of the dinitrogen monoxide.
