| abstract |
THE IMPACT RESISTANCE OF POLYPHENYLENE OXIDE IS MARKEDLY IMPROVED WITHOUT BEING IMPAIRED EXCELLENT CHARACTERISTICS THEREOF, SUCH AS HEAT RESISTANCE, CHEMICAL RESISTANCE, AND MECHANICAL AND ELECTRICAL PROPERTIES, BY BLENDING THEREWITH A GRAFT COPOLYMER OBTAINED FROM AN ETHYLENE-OLEFIN-POLYENE TERPOLYMER BY GRAFT- POLYMERIZING THEREON AT LEAST ONE STYRENE-TYPE COMPOUND IN AN AMOUNT OF 3 TO 90% BY WEIGHT BASED ON THE WEIGHT OF GRAFT COPOLYMER, IN SUCH A PROPORTION THAT THE AMOUNT OF ETHYLENE-A-POLYENE TERPOLYMER COMPONENT OF SAID GRAFT COPOLYMER IS 0.5 TO 15% BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE RESULTING COMPOSITION. |
