  • Processing polyethylene resins
    Patent number: 4603173
    Abstract: 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.

  • Ethylene polymer composition for blow molding
    Patent number: 4525322
    Abstract: Polyethylene blends for blow molding processes are disclosed, comprising from 12 to 25 weight percent of high molecular weight component, 5 to 83 weight percent of a medium molecular weight component, and 5 to 83 weight percent of the low molecular weight component, wherein the ratio of high molecular weight to medium molecular weight is greater or equal to 1.7 and the ratio of medium molecular weight to low molecular weight is greater or equal to 1.7, and wherein the blend has a melt index in the range of 0.01 to 2.0.
