Verfahren zur Herstellung eines vernetzten Materials aus Polymilchsäure und vernetztes Polymilchsäurematerial

摘要

A cross-linked material of polylactic acid produced by preparing a polylactic acid composition by mixing polylactic acid with at least a plasticizer containing either a rosin derivative or a dicarboxylic acid derivative and/or a glycerin derivative and cross-linking monomer, and kneading the resulting mixture; preparing a polylactic acid molded product by molding the composition into a desired shape; and then cross-linking the molded product by irradiation of ionizing radiation.
