- 4. The composition of claim 2, further comprising at least one functionalizing agent in amount up to about 8% by weight based on the weight of the poly(phenylene ether) resin.
- 5. The composition of claim 4, wherein the functionalizing agent is selected from the group consisting of functionalized olefinic compounds and non-polymeric polycarboxylic acids.
- 6. The composition of claim 4, further comprising at least one reinforcing filler present at a level from about 2% to about 50% by weight based on the total weight of the composition.
- 7. The composition of claim 4, wherein the reinforcing filler is selected from the group consisting of glass fibers, carbon fibers, potassium titanate single crystal fibers, aluminum oxide fibers, glass beads, hollow glass beads, wollastonites, talcs, micas, chalks, quartzes, natural kaolins, calcined kaolins, and mixtures thereof.
- 8. The composition according to claim 4, further comprising an impact modifier present at a level from about 2% to about 20% by weight based on the total weight of the composition.
- 9. The composition of claim 8, wherein the impact modifier is selected from the group consisting of:
- (i) block copolymers of alkenyl aromatic compounds and dienes;
- (ii) epoxy functional .alpha.-olefin elastomers; and
- (iii) a mixture of (i) and (ii).
- 10. The composition of claim 9, wherein the block copolymer is a triblock copolymer.
- 11. The composition of claim 10, wherein the block copolymer comprises polystyrene endblocks and a selectively hydrogenated diene-derived midblock.
- 12. The composition of claim 4, further comprising at least one alkenyl aromatic polymer.
- 13. An article made from a composition comprising:
- (a) a poly(phenylene ether) resin;
- (b) a poly(arylene sulfide) resin;
- (c) a polyester resin; and
- (d) a compatibilizer compound comprising at least two reactive groups selected from the group consisting of ortho ester, epoxy, or mixtures of ortho ester and epoxy, and
- wherein the poly(arylene sulfide) resin is present in a sufficient amount to be the continuous phase and wherein the polyester resin is present in an effective amount to provide a composition which exhibits increased tensile strength and tensile elongation over the same composition without the polyester resin.
- 14. A method for making a composition comprising: intimately admixing a poly(phenylene ether) resin, a poly(arylene sulfide) resin, a polyester resin, and a compatibilizer compound comprising at least two reactive groups selected from the group consisting of ortho ester, epoxy, or mixtures of ortho ester and epoxy, wherein the poly(arylene sulfide) resin is present in a sufficient amount to be the continuous phase and wherein the polyester resin is present in an effective amount to provide a composition which exhibits increased tensile strength and tensile elongation over the same composition without the polyester resin.
- 15. A composition consisting essentially of:
- (a) a functionalized poly(phenylene ether) resin;
- (b) a poly(arylene sulfide) resin;
- (c) a polyester resin; and
- (d) a compatibilizer compound comprising at least two reactive groups selected from the group consisting of ortho ester, epoxy, or mixtures of ortho ester and epoxy, and
- wherein the poly(arylene sulfide) resin is present in a sufficient amount to be the continuous phase and wherein the polyester resin is present in an effective amount to provide a composition which exhibits increased tensile strength and tensile elongation over the same composition without the polyester resin.
