<P>PROBLEM TO BE SOLVED: To provide a polyester block copolymer resin composition which excels in durability at the low temperature while having advanced moldability that is appropriate for thin wall molding, and further can maintain a stable property to environmental change, and to provide a molding. <P>SOLUTION: The polyester block copolymer resin composition is a resin composition which comprises blending 0.1-20 pts.wt. of a compatibilizer (C) based on 100 pts.wt. of a resin composition including 50-80 wt.% of a polyester block copolymer (A), and 20-50 wt.% of a hard resin (B), and further satisfies the all following conditions (1)-(3). (1) X<35 (I) Y/X>7 (II) (in the formula, X denotes viscosity (Pa s) measured by a shear rate of 30,000 sec<SP POS="POST">-1</SP>, and Y denotes viscosity (Pa s) measured by a shear rate of 500 sec<SP POS="POST">-1</SP>), (2) break energy is at least 20 J, and (3) a flexural modulus is at least 400 MPa. <P>COPYRIGHT: (C)2012,JPO&INPIT |
