Abstract
A process is provided to improve the properties of polyethylene resins obtained from chromium catalyzed polymerizations and blow molded bottles produced therefrom. The process entails modifying the polyethylene resin by contacting the resin in a molten state with an organic peroxide at a temperature above the decomposition temperature of peroxide. Polyethylene resins utilized for the process have specific densities, melt indexes, long chain branching indexes, unsaturation contents and molecular weight distributions. Blow molded bottles produced from the modified resins have significantly increased top load stress crack resistance and improved swell characteristics.
