Abstract

Provided is a polyamide resin composition which comprises a polyamide resin (A) and an impact-resistant material (B), wherein the polyamide resin (A) comprises an aliphatic copolyamide (A-1) comprising three or more types of monomers and an aliphatic polyamide (A-2), wherein the content of the aliphatic copolyamide (A-1) in the polyamide resin composition is 1% by mass to 30% by mass.

Claims (17)

1. A polyamide resin composition comprising a polyamide resin (A) and an impact-resistant material (B), wherein

the polyamide resin (A) comprises an aliphatic copolyamide (A-1) comprising three or more types of monomers and an aliphatic polyamide (A-2),

the content of the aliphatic copolyamide (A-1) in the polyamide resin composition is 1% by mass to 30% by mass, and

the polyamide resin composition further comprises an aromatic polyamide (A-3), wherein the content of the aromatic polyamide (A-3) in the polyamide resin composition is 1% by mass to 30% by mass, and the aromatic polyamide (A-3) is a polyamide 6T/6I.

2. The polyamide resin composition according to claim 1 , which has a copper antioxidant content of 1% by mass or less.

3. The polyamide resin composition according to claim 1 , which contains an organic antioxidant.

4. The polyamide resin composition according to claim 3 , wherein the content of the organic antioxidant in the polyamide resin composition is 0.05% by mass to 2% by mass.

5. The polyamide resin composition according to claim 3 , wherein the organic antioxidant is a phenolic antioxidant.

6. The composition according to claim 1 , wherein the aliphatic polyamide (A-2) comprises at least one member selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, polyamide 6/12, polyamide 610, polyamide 612, polyamide 11, and polyamide 12.

7. A molded article comprising the polyamide resin composition according to claim 1 .

8. The polyamide resin composition according to claim 2 , which contains an organic antioxidant.

9. The polyamide resin composition according to claim 8 , wherein the content of the organic antioxidant in the polyamide resin composition is 0.05% by mass to 2% by mass.

10. The polyamide resin composition according to claim 9 , wherein the organic antioxidant is a phenolic antioxidant.

11. The composition according to claim 2 , wherein the aliphatic polyamide (A-2) comprises at least one member selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, polyamide 6/12, polyamide 610, polyamide 612, polyamide 11, and polyamide 12.

12. A molded article comprising the polyamide resin composition according to claim 2 .

13. A molded article comprising the polyamide resin composition according to claim 3 .

14. A molded article comprising the polyamide resin composition according to claim 8 .
