Abstract

PURPOSE: To obtain a crosslinked polyethylene film having improved transparcency, by hot-drawing a polyethylene film containing 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide crosslinked with radiation.
CONSTITUTION: A composition comprising 100 parts by wt. of polyethylene resin and 0.01W5 parts by wt. of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is extruded into a tube. The molded article thus obtained is exposed to ionizing radiation to give a gel fraction of 3W80%, then hot-drawn at a temperature of the melting point of the resin (the lower one of the melting points when two or more types of resins are used) to 50°C higher than the melting point (the gigher one of the melting points to 50°C higher than the higher melting point when two or more types of resins are used) at an area draw ratio of 4W50 in at least one direction.
