POLYESTER RESIN COMPOSITION, COMPACT FORMED FROM SUCH RESIN COMPOSITION, AND METHOD FOR MANUFACTURING SUCH COMPACT

摘要

The purpose of the present invention is to improve processability in the melt-molding by improving the slowness of crystallization that is a disadvantage of polyhydroxyalkanoate, which is slow to crystallize, and to improve processing speed. Provided is a polyester resin composition including a first polyhydroxyalkanoate and a second polyhydroxyalkanoate, wherein the melting point of the second polyhydroxyalkanoate in the polyester resin composition is observed at a temperature lower than the melting point measured for the second polyhydroxyalkanoate alone.
