| 发明名称 | Polyamide resin composition and molded product | ||
| 摘要 | A polyamide resin composition includes 100 parts by weight of a (a) polyamide resin; and 0.1 to 10 parts by weight of a (b) hydroxyl group- and carboxyl group-containing compound, wherein the (b) hydroxyl group- and carboxyl group-containing compound has a ratio (COOH/OH) of 0.01 to 5.0 of a rate (percentage) of a carboxyl group-derived peak area to a total peak area in a 13C-NMR spectrum to a rate (percentage) of a hydroxyl group-derived peak area to a total peak area in a 1H-NMR spectrum and has a degree of branching of 0.05 to 0.35. | ||

| 主权项 | 1. A polyamide resin composition comprising: 100 parts by weight of a (a) polyamide resin; and 0.1 to 10 parts by weight of a (b) hydroxyl group- and carboxyl group-containing compound, wherein the (b) hydroxyl group- and carboxyl group-containing compound expressed by formula (1) and/or a condensate thereof: where R1 to R6 in formula (1) independently represent CH2OH, COOH or CH2,CH3, and n is 0 to 4, and having a ratio (COOH/OH) of 0.01 to 5.0 of a rate (percentage) of a carboxyl group-derived peak area to a total peak area in a 13C-NMR spectrum to a rate (percentage) of a hydroxyl group-derived peak area to a total peak area in a 1H-NMR spectrum and a degree of branching of 0.05 to 0.35. | ||
