1492204 Polyphenylene ether compositions MITSUBISHI GAS CHEMICAL CO Inc 16 Oct 1975 [18 Oct 1974] 42471/75 Headings C3R and C3P A thermoplastic composition comprises a blend of (1) 5 to 95% by weight of a copolymer having (i) 50 to 98 mole per cent of units and (ii) 50 to 2 mole per cent of units R1, R2, R3, R4 and R5 being methyl or ethyl groups, and (2) 95 to 5% by weight of a styrene resin having at least 50% of structural units of formula where R6 is hydrogen or methyl or ethyl, X is chlorine or bromine and m is 0, 1 or 2. In examples copolymers prepared by oxidative polymerization of mixtures of 2,6-dimethylphenol with 2,3,6-trimethylphenol and a mixture of 2,6-dimethylphenol with 2,3-dimethyl-6- ethylphenol, are blended with rubber modified polystyrene, a mixture of styrene/butadiene block copolymer with polystyrene, a styrene/ butadiene block copolymer, a mixture of polyisoprene with polystyrene, a mixture of an ethylene/propylene/5-ethylidene-norbornene copolymer with a styrene/ethylene/butylene copolymer, and a mixture of an acrylic rubber with a styrene/butadiene block copolymer and polystyrene; other ingredients are triphenyl phosphate, titanium oxide and a heat stabilizer.
