Claims
- 1. A polymer mixture, comprising:
- a) polyphenylene ether resin;
- b) polyamide resin;
- c) an agent to improve the impact strength of the polymer mixture, said agent comprising:
- i) 10-90 parts by weight of a partially hydrogenated vinylaromatic-diene-vinylaromatic diblock copolymer; and
- ii) 90-10 parts by weight of a partially hydrogenated diene-vinylaromatic polyblock copolymer having at least three blocks;
- wherein the parts of components (i) and (ii) are based on 100 parts of their total
- weight; and
- d) an agent to improve the compatibility of the polyphenylene ether and the polyamide.
- 2. The polymer mixture of claim 1, comprising 5-94% by weight of one or more polyphenylene ethers, 5-94% by weight of one or more polyamides, and 1-35% by weight of the impact strength agent.
- 3. The polymer mixture of claim 1, wherein the amount of diblock copolymer component (i) is greater than or equal to the amount of polyblock copolymer (ii).
- 4. The polymer mixture of claim 1, wherein the diblock copolymer of component (i) is a partially hydrogenated isoprene-styrene diblock copolymer.
- 5. The polymer mixture of claim 1, wherein the polyblock copolymer of component (ii) is a partially hydrogenated styrene-butadiene-styrene triblock copolymer or a partially hydrogenated styrene-isoprene-styrene triblock copolymer.
- 6. The polymer mixture of claim 1, wherein the compatibilizing agent of component (d) is selected from the group consisting of malic acid; citric acid; maleic anhydride; fumaric acid; derivatives of any of the foregoing; and functionalized polyphenylene ethers.
- 7. The polymer mixture of claim 1, further comprising at least one constituent selected from the group consisting of fillers, reinforcing fibers, flame-retardants, stabilizers; dyes, and pigments.
- 8. The polymer mixture of claim 1, wherein the polyphenylene ether resin is selected from the group consisting of poly(2,3,6-trimethylphenylene-1,4-ether); poly(2,6-dimethylphenylene-1,4-ether); and copolymers derived from at least two phenolic compounds.
- 9. A polymer mixture, comprising:
- a) 5-94% by weight poly(2,6-dimethylphenylene-1,4-ether);
- b) 5-94% by weight of a polyamide selected from the group consisting of polyamide-6; polyamide-4,6; polyamide-6,6; polyamide-11; polyamide-12; and polyamide-6,10;
- c) an agent to improve the impact strength of the polymer mixture, said agent comprising:
- i) 10-90 parts by weight of a partially hydrogenated isoprene-styrene diblock copolymer; and
- ii) 90-10 parts by weight of a partially hydrogenated styrene-isoprene-styrene triblock copolymer or a partially hydrogenated styrene-butadiene-styrene triblock copolymer;
- wherein the parts of components (i) and (ii) are based on 100 parts of their total
- weight; and
- d) a compatibilizing agent for components (a) and (b).
- 10. The composition of claim 9, wherein the compatibilizing agent is selected from the group consisting of malic acid; citric acid; maleic anhydride; fumaric acid; derivatives of any of the foregoing; and functionalized polyphenylene ethers.
