摘要： It is an object of the present invention to provide a novel production method which makes it possible to obtain a molded product containing a P3HB-based resin through an injection blow molding method and a technique for using such a method. The object is achieved by providing a method for producing a molded product containing a P3HB-based resin, the method including the steps of: (A) plasticizing a resin composition containing a P3HB-based resin; (B) subjecting the plasticized resin composition obtained in the step (A) to injection molding to obtain a preform; and (C) subjecting the preform obtained in the step (B) to blow molding to obtain a molded product.

摘要： A method for producing an injection-molded body from a molding material containing a poly(3-hydroxybutyrate) resin includes: melting the molding material by heating the molding material to a temperature between a melting point peak temperature and a melting point peak end temperature in differential scanning calorimetry analysis of the molding material, wherein the difference between the melting point peak temperature and the melting point peak end temperature of the molding material is from 10 to 70°C; injecting the molten molding material into a mold having a temperature of 30 to 80°C; and cooling the molding material in the mold to crystallize and solidify the molding material.
