[PROBLEMS] To improve the slow crystallization, which is a defect of a slow-crystallization P3HA copolymer among biodegradable polyesters, injection molding, film molding, blow molding, fiber spinning, extrusion foam molding, bead foaming. Improves workability in processing such as molding and increases processing speed. PHA produced from microorganisms, in particular formula (1): [—CHR—CH 2 —C O—O—] (wherein R is an alkyl group represented by C n H 2n + 1 , and n is an integer of 1 to 15, inclusive). A biodegradable polyester-based resin composition having a D value of 1.5 or more indicating a block property of a highly crystalline component. [Selection figure] None |
