摘要
An additive to a polyester base synthetic resin containing a plasticizer that comprises at least one compound selected from hydroxy aliphatic monocarboxylic acid ester and carboxylic acid amide is provided. Also, a polyester base synthetic resin composition comprising a polyester-base synthetic resin, a plasticizer, and at least one compound selected from hydroxy aliphatic monocarboxylic acid ester and carboxylic acid amide are also provided. Further, the invention provides a plasticizer for biodegradable resins that can impart flexibility without disturbing the transparency of the biodegradable resins. The plasticizer for biodegradable resins comprises a compound selected from (i) to (iii) below. A biodegradable composition comprises the plasticizer. (i) An ester selected from a hydroxy aromatic carboxylic acid ester and a hydroxy alicyclic carboxylic acid ester, (ii) a compound having a sulfonamide group, and (iii) an ester of a polycarbonate diol containing a structural unit (I) and having a hydroxy group at each of both ends with an aromatic monocarboxylic acid (II), condensed polycyclic aromatic monocarboxylic acid or the like. CHEM CHEM (wherein n denotes an integer of 2 to 6, X1 denotes H, OH, an alkyl group of C1-22 or the like, and m denotes an integer of 1 to 5.)
