    Abstract: a primary-crosslinking step in which a polylactic acid molding is crosslinked to produce a crosslinked polylactic acid; an impregnation step in which the crosslinked polylactic acid, which has been primarily crosslinked, is immersed in an impregnating material at a temperature not lower than the glass transition temperature of the polylactic acid and not higher than the melting point thereof; and a cooling step in which the crosslinked polylactic acid containing the impregnating material infiltrated therein is cooled in a swollen state to a temperature not higher than the glass transition temperature of the polylactic acid. After the cooling step, the polylactic acid may be secondarily crosslinked.

    Abstract: A molding material is provided to be formed into a desired shape by many molding methods, and to produce molded articles made of a biodegradable resin having heat resistance in a wide temperature range efficiently. A method for manufacturing a molding material includes a cross-linked biodegradable resin material powder manufacture step of producing a cross-linked biodegradable resin material powder by a process comprising the following steps of: (A) preparing a kneaded material containing a biodegradable resin component and a cross-linkable monomer; (B) cross-linking the biodegradable resin component to form a cross-linked biodegradable resin material(1); and (C) grinding the kneaded material or the cross-linked biodegradable resin material into powder.
