PURPOSE: To improve moldability and resistance to impact and oils and to reduce lowering in physical properties during the charge of inorg. filler by improving adhesion to the inorg. filler, by blending an ethylene copolymer with a polyphenylene ether. n CONSTITUTION: 1W50wt% ethylene copolymer is blended with 99W50wt% polyphenylene ether. Said ethylene copolymer is composed of 20W99wt% ethyl ene (A), 1W30wt% glycidyl ester of a conjugated unsaturated dicarboxylic acid (B) and 0W50wt% ethylenically unsaturated ester (C) of the formula (wherein R 1 is H, methyl; R 2 is -OCOR 3 or -COOR 4 ; R 3 , R 4 are each a 1W18C alkyl). Examples of component B are diglycidyl maleate and diglycidyl itaconate. Examples of component C are vinyl acetate, methyl acrylate and methyl methacrylate. n COPYRIGHT: (C)1986,JPO&Japio |
