Abstract:
1. A thermoplastic resin composition, prepared by a method comprising melt kneading a mixture of 1 to 95% by weight of a propylene-based polymer (A) and 5 to 99% by weight of a propylene-based copolymer (B), which is a copolymer of propylene and at least one α-olefin having 2 to 20 carbon atoms other than propylene, wherein the sum of (A) and (B) is 100% by weight, in the presence of an organic peroxide with a coupling agent (Y), wherein the amount of Y is 0.1 to 5 parts by weight relative to total 100 parts by weight of (A) and (B), and wherein (A) satisfies the following (i) and (ii), and (B) does not show a melting point as measured by a differential scanning calorimeter (DSC): (i) a melting point measured by a differential scanning calorimeter (DSC) method is in the range of 80 to 135° C.; and (ii) an endotherm attributable to crystal melting is not observed at 140° C. or more in the endothermic curve measured by a differential scanning calorimeter (DSC) method.
