Flame retardant polyphenylene ether resin compositions |
| abstract |
A polyphenylene ether resin composition comprising: (i) from about 30 to about 90 weight percent of a graft copolymer free from polyphenylene ether homopolymers prepared by polymerizing 20 to 200 parts by weight of styrene-type compound at a temperature in the range from 130 DEG C. to 200 DEG C. in the presence of 100 parts by weight of polyphenylene ether and 0.1 to 15 parts by weight of a radical initiator and (ii) 10 to 70 weight percent of a styrene-type compound polymer having a number average molecular weight in the range from 50,000 to 200,000; is rendered fire retardant by the addition of an effective amount of a phosphine oxide having the formula <IMAGE> wherein R1 may be the same or different radicals selected from the group consisting of hydrogen and the methyl radical, R2 is an alkyl radical of 4 to 8 carbon atoms and n is either zero or one. |
