Abstract: This invention aims at improving the tear strength of a film and a sheet molded from a resin composition containing microorganism-produced aliphatic polyester. This invention relates to a biodegradable polyester resin composition containing polybutylene adipate terephthalate (PBAT) in the proportion of 60 to 400 parts by weight and modified-glycerin in the proportion of 10 to 50 parts by weight based on 100 parts by weight of aliphatic polyester (P3HA) having a repeating unit represented by Formula (1): [—CHR—CH2—CO—O—] (wherein R is an alkyl group represented by CnH2n+1 and n is an integer of 1 or more and 15 or lower) and a film or a sheet obtained by molding the biodegradable polyester resin composition in which the maximum major axis of phases containing the aliphatic polyester (P3HA) measured by a transmission electron microscopy analysis-image analysis method (TEM method) is 18 μm or lower and the average value is 8 μm or lower.

Abstract: 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.

Abstract: An object is to increase crystallization speed, which is a drawback of polyhydroxyalkanoate, to improve processability in processing such as injection molding or blow molding and increase the speed of processing and is, in addition, to refine the crystal of polyhydroxyalkanoate to suppress a change of mechanical properties with passage of time of a resulting molded article. Disclosed herein is a polyester resin composition containing polyhydroxyalkanoate and pentaerythritol.
