Estimating the term…
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 comprising at least one transition metal compound and at least one organometallic co-catalyst compound and tetrahydrofuran 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.
A process for polymerizing an olefin and/or an olefin and at least one or more other olefin(s) comprising contacting, under polymerization conditions, the olefin and/or the olefin and at least one or more other olefin(s) with at least one Ziegler-Natta catalyst comprised of a component comprising at least one transition metal and a co-catalyst comprising at least one organometallic compound, and tetrahydrofuran, wherein the tetrahydrofuran is present in an amount sufficient to reduce the electrostatic charge in the polymerization medium.
A process for reducing electrostatic charge generated in the polymerization of an olefin and/or an olefin and at least one or more other olefin(s) in a polymerization medium in the presence of at least one Ziegler-Natta catalyst comprised of a component comprising at least one transition metal and a co-catalyst comprising at least one organometallic compound, comprising introducing into the polymerization medium tetrahydrofuran in an amount sufficient to reduce the electrostatic charge in the polymerization medium.
