PROBLEM TO BE SOLVED: To provide a nylon 12 composition excellent in flexibility, impact strength at a low temperature and creep characteristics. SOLUTION: This composition comprises (A) 100 pts.wt. of a nylon 12 which has a relative viscosity of 1.9-3.5 measured at a concentration of 10 g/dm3 in 98% sulfuric acid at 25 deg.C and a melt flow rate of at least 0.1 g/10 min measured at 235 deg.C under a load of 2,160 g, the relative viscosity and the melt flow rate satisfying the formula: 2.87×103 exp(-3.48ηr)<=MFR<=3.25×104 exp(-3.48ηr) (whereinηr is the relative viscosity and MFR is the melt flow rate), (B) 1-25 pts.wt. of a plasticizer and (C) 0-30 pts.wt. of a modified polyolefin comprising olefins composed mainly of ethylene and/or propylene and anα,β-unsaturated carboxylic acid or a derivative thereof. |
