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 an olefin polymerization 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.
Claims36
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 the olefin and at least one or more other olefin(s) with an olefin polymerization catalyst and dinitrogen monoxide, 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 dinitrogen monoxide.
A process for reducing electrostatic charge 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 an olefin polymerization catalyst, comprising introducing into the polymerization medium dinitrogen monoxide in an amount sufficient to reduce electrostatic charge in the polymerization medium to a level lower than would be obtained in the absence of dinitrogen monoxide.
