<P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition capable of giving a structure in which squeak noise generated when parts rub against each other is considerably reduced, while the reduction effect of the squeak noise is not deteriorated and kept even when being placed at a high temperature for a long time, and further, which has excellent shock resistance and molding appearance. <P>SOLUTION: The thermoplastic resin composition [X] contains a rubber reinforced vinyl based resin [A] obtained by polymerizing a vinyl monomer [b1] in the presence of an ethylene/α-olefine based rubber-like polymer [a1], wherein the content of [a1] is 5-30 mass% per 100 mass% of thermoplastic resin composition [X]; the tensile strength (Ts) of [a1] is 0.5-7 MPa; the elongation (EB) at break is ≥500%; the hardness (type A durometer) is 40-85; the Mooney viscosity (ML<SB POS="POST">1+4</SB>,<SB POS="POST">100°C</SB>) is 5-60; and the content of free rubber in the [X] is 1-30 mass%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
