Claims
- 1. A composition comprising a polycarbonate/polybutylene terephthalate (PC/PBT) alloy and a functional group-containing alkyl methacrylate-butadiene aromatic vinyl compound copolymer,
- wherein the functional group containing alkyl methacrylate-butadiene-aromatic vinyl compound copolymer is obtained from the following layers by emulsion graftlinking polymerization:
- (a) an inner layer comprising polybutadiene;
- (b) a middle layer comprising an aromatic vinyl compound and an alkyl methacrylate copolymer; and
- (c) an outer layer comprising an alkyl methacrylate and a functional group containing vinyl compound copolymer.
- 2. The composition according to claim 1, wherein the inner layer in said functional group containing copolymer comprises 20 to 80 wt. % of polybutadiene in the aromatic vinyl compound-butadiene copolymer.
- 3. The composition according to claim 2, wherein in the aromatic vinyl compound-butadiene copolymer, the aromatic vinyl compound is present in the amount of 0 to 50 wt. %.
- 4. The composition according to claim 1, wherein the middle layer contains 10 to 40 wt. % of the aromatic vinyl compound-alkyl methacrylate copolymer.
- 5. The composition according to claim 4, wherein the alkyl methacrylate is present in the amount of 20 to 80 wt. % of the aromatic vinyl compound.
- 6. The composition according to claim 1, wherein the outer layer contains 10 to 40 wt. % of the alkyl methacrylate-functional group-containing vinyl compound copolymer.
- 7. The composition according to claim 6, wherein the functional group-containing vinyl compound is present in the amount of 1 to 20 wt. % of the alkyl methacrylate.
- 8. The composition according to claim 1, wherein the aromatic vinyl compound is selected from the group consisting of styrene, .varies.-methyl styrene and .rho.-methyl styrene.
- 9. The composition according to claim 1, wherein the alkyl methacrylate is selected from the group consisting of methyl methacrylate, isopropyl methacrylate, 2-butyl methacrylate and t-butyl methacrylate.
- 10. The composition according to claim 1, wherein the functional group-containing vinyl compound is an amide or amino group-containing compound.
- 11. The composition according to claim 10, wherein the functional group-containing vinyl compound is selected from the group consisting of acrylamide, N-methylol acrylamide and 2-dimethylamino ethyl methacrylate.
- 12. The composition according to claim 1, wherein the functional group-containing vinyl compound is a carboxyl group-containing compound.
- 13. The composition according to claim 12, wherein the functional group-containing vinyl compound is selected from the group consisting of acrylic acid, methacrylic acid, maleic anhydride and itaconic acid.
- 14. The composition according to claim 1, wherein the functional group-containing vinyl compound is a chloro methyl phenyl group-containing compound.
- 15. The composition according to claim 14, wherein the functional group-containing vinyl compound is chloro methyl styrene.
- 16. The composition according to claim 1, wherein the functional group-containing vinyl compound is an epoxy group-containing compound.
- 17. The composition according to claim 16, wherein the functional group-containing vinyl compound is glycidyl methacrylate.
- 18. The composition according to claim 1, wherein the functional group-containing vinyl compound is a hydroxy group-containing compound.
- 19. The composition according to claim 18, wherein the functional group-containing vinyl compound is selected from the group consisting of 2-hydroxy ethyl methacrylate and 2-hydroxyl propyl methacrylate.
