Abstract

PURPOSE: To prepare a highly crystalline polyolefin resin molded article having low brittle temperature without lowering the crystallinity, by heat treating a partially cross-linked olyolefin resin molded article at high pressure.
CONSTITUTION: A polyolefin resin such as polyethylene is cross-linked by electron- beam cross-linking, chemical cross-linding, etc., to give a gel fraction of ≤10%, and heated at a temperature between 20°C below the melting point and 20°C above the melting point for, e.g. 10W20 min. under a pressure of, e.g. 2500W5000 kg/cm2 in silicone oil.
