THERMOPLASTIC RESIN COMPOSITION FOR REDUCING CREAK AND CREAK REDUCTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition capable of providing a structure extremely reducing creak generated when components are rubbed each other, maintaining creak reduction effects even when standing it under high temperature for long time and further excellent in impact resistance and molding appearance.SOLUTION: A thermoplastic resin composition [X] for reducing creak contains a rubber reinforced vinyl resin [A] obtained by polymerizing a vinyl monomer [b1] in presence of an ethylene α-olefin rubbery polymer [a1] having Tm (melting point) of 0°C or more and a silicone oil, and has Mooey viscosity (ML1+4, 100°C; according to JIS K6300) of the ethylene α-olefin rubbery polymer [a1] having Tm (melting point) of 0°C or more of 5 to 80. The silicon content derived from the silicone oil in the thermoplastic resin composition [X] is 0.15 mass% or less based on 100 mass% of the thermoplastic resin composition [X].SELECTED DRAWING: None
