To obtain the subject resin composition for molding materials, comprising a polyketone resin, a polycarbonate resin and a block copolymer having a specific functional group, excellent in mechanical strength such as tensile strength, flexural strength or flexural modulus.
This thermoplastic resin composition is obtained by blending 100 pts.wt. resin mixture comprising (A) 10-90 pts.wt. polyketone resin comprising a structural unit of the formula (A is a unit derived from an olefin) and (B) 90-10 pts.wt. polycarbonate resin with (C) 0.1-20 pts.wt. block copolymer composed of (i) a polymer block comprising 30-100mol% aromatic vinyl-based monomer unit and 70-0mo1% vinyl-based monomer unit copolymerizable therewith, (ii) a polymer block comprising 0.1-100% vinyl-based monomer unit having at least one kind of functional group selected from carboxyl group epoxy group and carboxylic acid anhydride group and 99.9-0% vinylbased monomer unit copolymerizable therewith.
