摘要： The present invention provides a method for manufacturing a resin composition by which a polyester resin composition with excellent mechanical properties can be manufactured at low cost, and a resin composition manufactured thereby. A raw material composition containing a polyester resin, a polyolefin resin and a compatibilizer is kneaded in the presence of moisture. Each of the components may be mixed so as to prepare the raw material composition and kneaded thereafter, or may be mixed during the kneading so as to obtain the raw material composition. The raw material composition may contain an additive such as a plant tissue-derived component and an inorganic filler, as necessary. Moreover, in the kneading step, the kneading preferably is conducted while at least one of the components of the raw material composition except the moisture is added into the raw material composition, as necessary.

摘要： A manufacturing process for a resin composition is provided, whereby it is possible to homogeneously knead particles and low-temperature decomposable additives into resins. First of all, a thermoplastic resin and an additive are pre-heated and mixed together, after which transition to the kneading step is carried out while the mixture is maintained in a heated state. Then, the mixture is kneaded under heating and molded by extrusion molding or the like to obtain the target resin composition. In the present invention, additives used in particulate form are not liable to cake and can be homogeneously kneaded in because the transition to the kneading step is carried out while the mixture is maintained in a heated state. Moreover, it is possible to knead in low-temperature decomposable additives because the heating temperature used for kneading can be reduced significantly in comparison with the conventional art.
