PURPOSE: To obtain the titled compsn. having mechanical strength and heat resistance, by blending an ethylene/α-olefin copolymer resin, an unsaturated acid-modified olefin polymer and a flame retarder. n CONSTITUTION: A polymer compsn. contains 5W200pts.wt. flame retarder and 100pts.wt. resin component consisting of 99W60wt% copolymer (a) of ethylene with a carboxyl group-contg. monomer or its derivative and 1W40wt% olefin polymer (b) modified with an unsaturated carboxylic acid or its derivative. Preferred examples of component (a) are ethylene/acrylic acid copolymer, ionomer resins and ethylene/vinyl acetate copolymer. Said polymer has a melt index of 0.1W10g/10min, pref. 0.3W5g/10min. n COPYRIGHT: (C)1987,JPO&Japio |
