摘要：
Polyethylene blow molding resins having improved processing properties such as reduction of flare swell and die swell are obtained by treating resins having particular molecular weight characteristics with low levels of free radical initiators. The free radical initiators are used at such low levels that the final physical properties of the resins are substantially unchanged, yet processing is greatly improved.
