The gist of the present invention resides in a graft copolymer having a rubber component containing a polyorganosiloxane and having a content of 3 to 7-membered dimethylsiloxane-based cyclic body of 3000 ppm or less, and when added to a thermoplastic resin. In addition to exhibiting excellent impact resistance and the like, there is little residual volatile content in the molded product, and the significance of its existence is very large particularly in applications such as automobile interiors and building interior members. The graft copolymer of the present invention is a thermoplastic resin selected from polycarbonate resins, styrene resins, acrylonitrile / styrene resins, polyester resins, polyamide resins, polyacetal resins, and polyphenylene ether resins. Or it is used especially suitably for resin which consists of 2 or more types. |
