ABSTRACT:
The content of spherulites of polyethylene resins is reduced by contact of the polyethylene resin while it is molten with lithium carbonate which is in a subdivided form and is dispersed in the molten polyethylene resin or which is in a form of a block and is removed from the polyethylene resin after the contact. The dispersed lithium carbonate can be removed with the reduced spherulite content preserved.
