Claims
- 1. A method for the manufacture of a polyphenylene ether-polyamide composition comprising:
- (A)
- (i) 5 to 94 percent by weight of a polyphenylene ether and
- (ii) 5 to 94 percent by weight of a polyamide, wherein the percent by weight of the polyphenylene ether and the polyamide are based on the weight of the entire composition;
- (B) one or more compatibilizing agents in an amount sufficient to effect compatibilization between (A) (i) and (A) (ii) and wherein the one or more compatibilizing agents are selected from the group consisting of:
- (i) liquid diene polymers;
- (ii) epoxy compounds;
- (iii) compounds having in their molecular structure a double or triple carbon-to-carbon bond and a carboxylic acid, anhydride, ester, amide, imido, amino, or hydroxyl group;
- (iv) a copolymer having units of a vinylaromatic compound and an alpha, beta-unsaturated dicarboxylic acid or dicarboxylic acid anhydride; and
- (v) a copolymer with units of a vinyl aromatic compound and of an imide compound of an alpha, beta unsaturated dicarboxylic acid; and
- (C) 1 to 50 percent by weight of at least one olefinic based agent to improve the impact resistance of the composition wherein the olefinic based agent is an ethylene-propylene copolymer or an ethylene-propylene-non-conjugated diene terpolymer on which a vinyl monomer with a carboxylic acid group or a derivative thereof has been grafted, or on which a vinyl monomer with an epoxy group has been grafted, and (A) and (C) add up to 100 parts by weight;
- wherein the method comprises mixing as a melt the polyphenylene ether and the one or more compatibilizing agents before the polyphenylene ether is mixed with the polyamide and the olefinic based agent to improve the impact resistance of the composition.
- 2. The method of claim 1, wherein the olefinic based agent to improve the impact resistance of the composition is an olefinic based agent to which maleic anhydride has been grafted.
- 3. The method of claim 1, wherein the polyamide comprises polyamide-6.
- 4. The method of claim 1, wherein the polyamide comprises polyamide-6,6.
- 5. The method of claim 1, wherein the compatibilizing agent comprises maleic anhydride.
- 6. The polyphenylene ether-polyamide composition made by the method of claim 1.
- 7. A method for the manufacture of a polyphenylene ether-polyamide composition comprising:
- (A)
- (i) 5 to 94 percent by weight of a polyphenylene ether and
- (ii) 5 to 94 percent by weight of a polyamide, wherein the percent by weight of the polyphenylene ether and the polyamide are based on the weight of the entire composition;
- (B) one or more compatibilizing agents in an amount sufficient to effect compatibilization between (A) (i) and (A) (ii) and wherein the one or more compatibilizing agents are selected from the group consisting of:
- (i) liquid diene polymers;
- (ii) epoxy compounds;
- (iii) compounds having in their molecular structure a double or triple carbon-to-carbon bond and a carboxylic acid, anhydride, ester, amide, imido, amino, or hydroxyl group;
- (iv) a copolymer having units of a vinylaromatic compound and an alpha, beta-unsaturated dicarboxylic acid or dicarboxylic acid anhydride; and
- (v) a copolymer with units of a vinyl aromatic compound and of an imide compound of an alpha, beta unsaturated dicarboxylic acid; and
- (C) 1 to 50 percent by weight of at least one olefinic based agent to improve the impact resistance of the composition wherein the olefinic based agent is an ethylene-propylene copolymer or an ethylene-propylene-non-conjugated diene terpolymer on which a vinyl monomer with a carboxylic acid group or a derivative thereof has been grafted, or on which a vinyl monomer with an epoxy group has been grafted, and (A) and (C) add up to 100 parts by weight;
- wherein the method comprises mixing as a melt the polyphenylene ether, the one or more compatibilizing agents, the polyamide, and the olefinic based agent to improve the impact resistance of the composition.
- 8. The method of claim 7, wherein the olefinic based agent to improve the impact resistance of the composition is an olefinic based agent to which maleic anhydride has been grafted.
- 9. The method of claim 7, wherein the polyamide comprises polyamide-6.
- 10. The method of claim 7, wherein the polyamide comprises polyamide-6,6.
- 11. The method of claim 7, wherein the compatibilizing agent comprises maleic anhydride.
- 12. The polyphenylene ether-polyamide composition made by the method of claim 7.
