| titleOfInvention | Method for preparing biodegradable aliphatic-aromatic polyester copolymer resin with improved hydrolysis resistance |
| abstract | There is provided a method of preparation for a biodegradable co-polyester resin with improved hydrolysis resistance, the method including performing a primary esterification reaction between an aliphatic dihydroxy compound and an aliphatic dicarboxylic acid compound, and performing a secondary transesterification reaction with addition of an aromatic dicarboxylate after the primary esterification reaction, in which a short chain alcohol-type branching agent is added to the primary esterification reaction or to the secondary transesterification reaction. In the method of the present invention, the slow esterification reaction caused by acid is performed first and the aromatic dicarboxylate compound without acidity is added thereto, thereby efficiently controlling a non-reactant or a partial-reactant affecting an acid value of a product during the reaction, so that an acid value can be controlled and hydrolysis resistance can be improved without using an excessive amount of expensive BDO, an reaction of an excessive amount of a chain extender, or using an expensive anti-hydrolysis agent. Further, by minimizing an amount of the branching agent used herein, tear strength can be improved. |
