PURPOSE:A resin composition excellent in impact resistance, heat resistance, flexibility, moldability, etc., comprising a polyamide resin and a modified polyolefin having a specified functional group. CONSTITUTION:A resin composition comprising 5-98wt% polyamide resin (e.g., nylon 6 or 66) and a modified polyolefin containing 0.001-10mol% at least one functional group selected from among those of formulas I , II, and III (wherein R1-R5 are each H or an organic group), e.g., ethylene/proplylene compolymer having 0.18mol% functional groups of formula IV in side chains. Because the above functional groups contain imido, amido, or like groups and are similar in structure to units constituting a polyamide, this modified polyolefin shows good compatibility with a polyamide. Therefore, it is possible to obtain a resin composition having well-balanced excellent impact resistance, heat resistance, flexibility, fluidity etc. |
