摘要

PROBLEM TO BE SOLVED: To provide styrene-modified polyethylene resin particles excellent in thermal resistance.;SOLUTION: Styrene-modified polyethylene resin particles contain 100 pts.mass of polyethylene resin, and 20-600 pts.mass of polystyrene resin. The polyethylene resin has: a Z average molecular weight of 1,300,000-3,000,000; a dispersion of 5-10; and a density of 940-970 kg/m³.;COPYRIGHT: (C)2013,JPO&INPIT
