Claims
- 1. A blended composition comprising:
- (a) a preblend of a modified styrenic polymer wherein said modified styrenic polymer comprises the reaction product of polybutadiene modified styrene acrylonitrile resin with an ethylenically unsaturated grafting agent, said grafting agent being maleic anhydride and said modified styrenic polymer containing the acid anhydride groups of said maleic anhydride as pendant reactive functionalities, and a rubber and
- (b) a polyester.
- 2. The blended composition of claim 1 wherein said polyester is polyethylene terephthalate.
- 3. The blended composition of claim 1 wherein said rubber is functionalized ethylene copolymer.
- 4. The blended composition of claim 3 wherein said functionalized ethylene copolymer is functionalized ethylene-propylene rubber.
- 5. The blended composition of claim 4 wherein said functionalized ethylene-propylene rubber is functionalized with maleic anhydride.
- 6. The blended composition of claim 1 wherein said rubber is ethylene/ethylacrylate/glycidyl methacrylate terpolymer.
- 7. The blended composition of claim 1 wherein said polyester is poly(butylene terephthalate).
- 8. The blended composition of claim 1 wherein said polyester is poly(1,4-cyclohexane dimethylene terephthalate).
