Claims
- 1. A thermoplastic composition having improved impact strength and melt behavior consisting essentially of:
- (a) a polyphenylene ether resin having an intrinsic viscosity less than approximately, 0.42 dl/g as measured in chloroform at 25.degree. C.;
- (b) a compound of the formula R-SO .sub.3 X wherein R represents an alkyl or aralkyl radical having 5 to 25 carbon atoms and X represents an alkali metal ion, in an amount effective for improving the melt behavior of said polyphenylene ether resin; and
- (c) an impact strength improving amount of an acrylate-styrene-acrylonitrile terpolymer.
- 2. A composition as in claim 1 wherein the compound of formula R-SO.sub.3 X is present in an amount of, approximately, 0.5 to 5.0 parts by weight per 100 parts of the polyphenylene ether resin.
- 3. A composition as in claim 1 wherein the acrylate-styrene-acrylonitrile terpolymer is present in an amount of, approximately, 1 to 20 parts of the polyphenylene ether resin.
- 4. A composition as in claim 1 wherein the acrylate-styrene-acrylonitrile terpolymer is comprised of, approximately, 5 to 50 weight percent of at least one crosslinked acrylate, 5 to 35 weight percent crosslinked styrene-acrylonitrile, and 15 to 90 weight percent uncrosslinked styrene-acrylonitrile.
- 5. A composition as in claim 1 wherein the compound of formula R--SO.sub.3 X is a mixture of compounds having said formula and R represents alkyl radicals independently having 12 to 20 carbon atoms.
- 6. A composition as in claim 1 wherein in the formula R--SO.sub.3 X, X represents a sodium ion.
- 7. A composition as in claim 1 wherein the polyphenylene ether is a homopolymer or a copolymer.
- 8. A composition as in claim 7 wherein the polyphenylene ether is poly(2,6-dimethyl-1,4-phenylene)ether.
- 9. A composition as in claim 1 wherein the polyphenylene ether has an intrinsic viscosity of approximately, 0.38 to 0.42 dl/g.
- 10. A molded article comprised of the thermoplastic composition of claim 1.
