Abstract
A preblend of one or more pigments and one or more polymers derived from ethylene monomers and α-olefin monomers when added to polyethylene unexpectedly results in high improvements in impact strength with regard to rotationally molded products as compared to the same products not blended with any preblend. The result is a cost effective, high impact resistant polyethylene that is a physical, dry color blend.
