Abstract: Poly(3-hydroxyalkanoate) foam particles are obtained by: introducing a blowing agent into an aqueous dispersion in a pressure-resistant vessel, the aqueous dispersion containing a crosslinking agent and resin particles containing a poly(3-hydroxyalkanoate); heating the contents of the pressure-resistant vessel to a given temperature in a range of 130 to 150° C.; holding the contents of the pressure-resistant vessel at the given temperature for 5 to 55 minutes; and opening one end of the pressure-resistant vessel to discharge the contents of the pressure-resistant vessel into a low-pressure atmosphere and foam the resin particles. The poly(3-hydroxyalkanoate) is a mixture containing a poly(3-hydroxyalkanoate) copolymer and a poly(3-hydroxybutyrate) homopolymer at a weight ratio of 99:1 to 80:20, and the crosslinking agent is an organic peroxide which is a percarbonate.

Abstract: A PHA copolymer which is slowly crystallized is improved in crystallization speed to improve the melt workability of the PHA copolymer in working such as injection molding, film molding, blow molding, fiber spinning, extrusion foaming or bead foaming, thereby improving the resultant articles in productivity. A method for the improvement is a method for producing a PHA mixture, including the step of culturing a microorganism having both of a gene encoding a PHA synthase that synthesizes a copolymer PHA (A) and that is derived from the genus Aeromonas, and a gene encoding a PHA synthase that synthesizes a PHA (B) different in melting point from the copolymer PHA (A) by 10° C. or more to produce, in a cell of the microorganism, two or more PHAs different in melting point from one another by 10° C. or more simultaneously.
