Patent ID: 8067499

Claim:
A thermoplastic resin composition comprising 1 to 95% by weight of a propylene-based polymer (AA) and 5 to 99% by weight of a propylene-based copolymer (BB), which is a copolymer of propylene and at least one α-olefin having 2 to 20 carbon atoms other than propylene, wherein (AA) satisfies the following (ia) and (iia), and (BB) satisfies the following (ib) and (iib): (ia) a melting point measured by a differential scanning calorimeter (DSC) method is 80° C. or more and 140° C. or less; (iia) a molecular weight distribution measured by a gel permeation chromatography is 3 or less; and (ib) no melting point is observed as measured by a differential scanning calorimeter; (iib) a triad tacticity (mm fraction) as measured by 13 C—NMR is 85% or more.
