There are provided: a shape-memory resin, which is formed from a polylactic acid derivative thereby enabling reduction of an environmental load, has an excellent shape-memory property, high strength, and high toughness, and with which a molded product with high durability, for example, an electronic equipments, particularly a wearable electronic equipments capable of freely changing the shape thereof or the like, can be shaped; and a molded product thereof. The shape-memory resin of the present invention has a three-dimensional structure, in which a polylactic acid derivative having two or more functional groups capable of forming a cross-linking site is cross-linked using a flexible polymer having a glass transition temperature (Tg) lower than 30° C. and having two or more functional groups capable of forming a cross-linking site, and a linker.

The reactions are disclosed of furfuryl alcohol in the presence of catalyst with aliphatic diacid esters or aliphatic diacid anhydrides to synthesize diesters and monoesters, respectively. The reaction is disclosed of the monoester in the presence of catalyst with alkanols to synthesize diesters. The two types of diesters and the monoesters are proven to be suitable as plasticizers for polymers, particularly polylactic acid. Thermoplastic compounds are disclosed using the esters as plasticizers.
