POLYETHYLENE WITH IONOMERIC GROUPS FOR INCREASED ENVIRONMENTAL STRESS CRACKING RESISTANCE

摘要

A polyethylene composition having increased environmental stress crack resistance comprises a polymer blend of a multimodal high density polyethylene (HOPE) and an ionomeric polyethylene. In a method of forming a polyethylene composition having increased environmental stress crack resistance, a multimodal high density polyethylene (HOPE) is modified by combining the multimodal HOPE with an ionomeric polyethylene.
