Plasticizer and method for manufacturing the same

Abstract

A plasticizer and a method for manufacturing the plasticizer are provided. The method includes the following steps. A dicarboxylic acid, a diol, and a catalyst are mixed to form a reactant mixture. The reactant mixture is reacted at a temperature ranging from 130° C. to 220° C. to form a semi-product. An endcapping alcohol is added into the semi-product at a temperature ranging from 205° C. to 220° C. to form a coarse plasticizer. The coarse plasticizer is purified under a pressure ranging from 760 Torr to 5 Torr to obtain the plasticizer. The dicarboxylic acid includes succinic acid or adipic acid. The diol includes diethylene glycol and 2-methyl-1,3-propanediol. The endcapping alcohol is an ether alcohol or a fatty alcohol having a carbon number of less than or equal to 4. The dicarboxylic acid, the diol, and the endcapping alcohol have a molar ratio ranging from 1:0.6 to 0.9:0.3 to 0.6.
