Method of making a morphology-improved polyethylene powder

Abstract

A method of making a morphology-improved polyethylene powder, the method comprising: contacting ethylene with a reactive olefin prepolymer in a gas phase reactor to make a morphology-improved polyethylene powder via gas phase polymerization; wherein the reactive olefin prepolymer comprises a component that is a polyolefin and a component that is an active metallocene derivative of a spray-dried silica-supported metallocene catalyst; wherein the reactive olefin prepolymer has a prepolymer/catalyst weight/weight ratio from 10:1.0 to 50:1.0, wherein the prepolymer weight is the total weight of the reactive olefin prepolymer and the catalyst weight is the weight of the spray-dried silica-supported metallocene catalyst.
