- 3. A resin composition as defined in claim 1, wherein the ABS graft copolymer comprises at least 40 wt. % of the vinyl aromatic compound and the acrylonitrile compound, and up to 60 wt. % of a rubber substrate.
- 4. A composition as defined in claim 1, wherein the weight ration of the acrylonitrile compound to the vinyl aromatic compound is 20:80 to 40:60.
- 5. A composition as defined in claim 1, wherein the acrylonitrile compound is acrylonitrile, a halogenated acrylonitrile, methacrylonitrile, ethacrylonitrile or an alkylacrylonitrile.

- 10. A composition as defined in claim 9, wherein the alkylene oxide is propylene oxide or 1-butene oxide.
- 11. A composition as defined in claim 9, wherein the aromatic substituted epoxide is styrene oxide or alphamethylstyrene oxide.
- 12. A composition as defined in claim 9, wherein the halogen-substituted alkylene oxide is epichlorohydrin or epibromohydrin.
- 13. A composition as defined in claim 9, wherein the alkenyl glycidyl ether is allyl glycidyl ether.
- 14. A composition as defined in claim 9, wherein the aromatic glycidyl ether is phenyl glycidyl ether.
- 15. A composition as defined in claim 9, wherein the glycidyl ester is glycidyl acetate, glycidyl propionate, glycidyl methacrylate or glycidyl benzoate.
