Provided are blends of linear low density polyethylene copolymers with very low density, low density, medium density, high density, and differentiated polyethylenes and other polymers. The invention also includes articles produced from the linear low density polyethylene and polyethylene blends described herein.

Linear polymers, polymer blends, and articles made therefrom

A suspending agent system, a polymerizable reaction mixture, and a polymerization reaction process for producing high bulk density resin on a consistent basis by incorporating in the reaction mixture prior to initiation of the reaction about 1-250 parts per million by weight of polymerization inhibitor and also including about 0.001-0.1 parts by weight based on the weight of VCM of a highly hydrolyzed PVA. Preferred PVA's have a 4 weight percent aqueous solution viscosity of 30-100 centipoise and an effective polymerization inhibitor is diethylhydroxylamine. Bulk densities may be increased from about 3-10% depending upon the size of the reaction and the particular ingredients chosen.
