Claims
- 1. A composition of matter consisting essentially of, in admixture,
- (a) an aromatic polycarbonate,
- (b) a crystalline aromatic polyester,
- (c) a thermoplastic epoxide-containing copolymer, having a glass transition temperature of less than 0.degree. C., prepared from (i) one or more olefin monomers, and (ii) at least one vinyl monomer carrying at least one epoxide group, and
- (d) a rubber-modified styrene/acrylonitrile copolymer containing 1 to 25 percent rubber by weight and optionally a filler.
- 2. The composition of claim 1 wherein the rubber portion of the styrene/acrylonitrile copolymer comprises one or members of the group consisting of a butadiene, ethylene/propylene/diene copolymer and an alkyl acrylate.
- 3. The composition of claim 1 wherein the rubber-modified styrene/acrylonitrile copolymer is a mass produced acrylonitrile/butadiene/styrene copolymer.
- 4. The composition of claim 1 wherein the rubber-modified styrene/acrylonitrile copolymer is a mass produced acrylonitrile/EPDM/styrene copolymer where EPDM is ethylene/propylene/diene copolymer.
- 5. The composition of claim 1 wherein the rubber-modified styrene/acrylonitrile copolymer contains 1 to 20 percent rubber by weight.
- 6. The composition of claim 1 wherein the rubber-modified styrene/acrylonitrile copolymer contains 1 to 10 percent rubber by weight.
- 7. The composition of claim 1 which contains a filler.
- 8. The composition of claim 7 wherein the filler is talc, clay, mica, glass or a mixture thereof.
- 9. The composition of claim 1 in the form of a molded article.
- 10. The composition of claim 1 wherein component (c) further comprises (c) (iii) at least one vinyl monomer not carrying an epoxide group.
- 11. The composition of claim 10 wherein component (c) (iii), at least one vinyl monomer not carrying an epoxide group, is grafted as a polymer chain to component (c), the epoxide-containing copolymer.
- 12. The composition of claim 11 wherein said grafted polymer chain comprises styrene, acrylonitrile, vinyl acetate, methyl methacrylate, or a mixture thereof.
- 13. The composition of claim 10 wherein the rubber portion of the styrene/acrylonitrile copolymer comprises one or members of the group consisting of a butadiene, ethylene/propylene/diene copolymer and an alkyl acrylate.
- 14. The composition of claim 10 wherein the rubber-modified styrene/acrylonitrile copolymer is a mass produced acrylonitrile/butadiene/styrene copolymer.
- 15. The composition of claim 10 wherein the rubber-modified styrene/acrylonitrile copolymer is a mass produced acrylonitrile/EPDM/styrene copolymer where EPDM is ethylene/propylene/diene copolymer.
- 16. The composition of claim 10 wherein the rubber-modified styrene/acrylonitrile copolymer contains 1 to 20 percent rubber by weight.
- 17. The composition of claim 10 wherein the rubber-modified styrene/acrylonitrile copolymer contains 1 to 10 percent rubber by weight.
- 18. The composition of claim 10 which contains a filler.
- 19. The composition of claim 18 wherein the filler is talc, clay, mica, glass or a mixture thereof.
- 20. The composition of claim 10 in the form of a molded article.
