PROBLEM TO BE SOLVED: To obtain both a thermoplastic resin composition capable of producing a molded product such as a film or a sheet having excellent elongation at a low stress, high recovery stress after elongation and a low residual strain after elongation and a molded product comprising the composition. SOLUTION: The thermoplastic resin composition comprises (a) a thermoplastic polyurethane comprising a polymer polyol unit having 2.01-2.10 hydroxyl groups per molecule and 500-8,000 number-average molecular weight, an organic diisocyanate unit and a chain extender unit, (b) an ethylene-α-olefin copolymer having a molar ratio of ethylene unit/α-olefin unit of 75/25-95/5 and (c) an polyolefin-based resin having 0.01-0.3 g/10 minutes melt index. In this case, the composition includes 30-90 wt.% of the component (a), 70-10 wt.% of the component (b) and 5-17 wt.% of the component (c) based on the total of the components (a) and (b). The molded product is obtained from the composition. |
