20090176900 | FOAMED POLYHYDROXYALKANOATE RESIN PARTICLES AND METHOD OF PRODUCING THE FOAMED PARTICLES - It is intended to provide an easy-to-use, energy-saving and economical method of producing foamed resin particles having a high environmental compatibility by using an ether, which generates neither sulfur oxide nor sot in the course of disposal and incineration and enables considerable reduction in nitrogen oxide formation, and further using a resin which originates in a plant and contributes to the carbon dioxide fixation. Namely, a method of producing foamed P3HA resin particles comprising the step of feeding particles of a resin containing a copolymer, which is produced by a microorganism and has a repeating unit represented by the general formula (1) [—CHR—CH | 07-09-2009 |
