By introducing a covalently bondable thermoreversible crosslinked structure into the biodegradable resin, a biodegradable resin having sufficient heat resistance, moldability and recyclability can be obtained without impairing biodegradability. If necessary, the heat resistance, moldability, recyclability and biodegradability can be further improved by setting the dissociation temperature of the cross-linked structure within a predetermined range, selecting the type of cross-linked structure, and making the cross-linked structure tertiary. |
