Method for producing thermoplastic resin compound.

摘要

With the aim of preventing deterioration in properties of resins in the production of a thermoplastic resin compound by melting and kneading a polyester resin and a polyphenylene ether resin, a method for producing the thermoplastic resin compound comprising 30 to 70 % by weight of a polyester resin (A) mainly comprising polyalkylene terephthalate and 70 to 30 % by weight of a polyphenylene ether resin (B) mainly comprising polyphenylene ether comprises separately melting the component (A) and the component (B) and, after adjusting the ratio of viscosity (in poise) of the component (B) to that of the component (A) at a shear rate of 10<3>(sec<-><1>) to 10 or less, kneading the molten components (A) and (B) together.
