POLYAMIDE RESIN COMPOSITION |
摘要 |
A polyamide resin composition comprising 100 parts by weight of a polyamide resin and 5-200 parts by weight of a graft ethylene-1-butene random copolymer wherein the content of an unsaturated carboxylic acid or a derivative thereof as the graft component is 0.01-10 wt.%. The graft copolymer is one prepared by grafting an ethylene-1-butene random copolymer having a 1-butene content of 15-25 mole%, a limiting viscosity [ eta ] of 0.5-3.5 dl/g, a glass transition point of -60 DEG C or below, a crystallinity of less than 10 %, and a parameter (B value) indicative of the randomness of comonomer chain distribution as determined by <13>C-NMR spectrometry of 1.0 to 1.4. The composition is excellent in melt flow, i.e., moldability, and can provide moldings excellent in flexibility and resistances to low-temperature impact, water absorption and chlorine water. |
