Abstract
A graft modified polyethylene process is described which comprises contacting polyethylene with an organic peroxide in the presence of an ethylenically unsaturated polycarboxylic acid or derivative thereof at a temperature of from 140.degree.-210.degree. C. The resulting graft modified polyethylene in combination with polyamides provide polymer blends having improved impact properties.
