PURPOSE: A biodegradable aliphatic/aromatic copolyester resin composition is provided to manufacture all kinds of molded product such as extrusion and injection molded products by solving problems regarding physical properties, processability, reaction rate, and short lifetime of existing biodegradable resins. CONSTITUTION: A biodegradable aliphatic/aromatic copolyester resin composition is prepared by mixing an aliphatic dicarboxylic acid or anhydride thereof and an acid components mixture of aromatic dicarboxylic acid or anhydride thereof indicated in chemical formula 1, aliphatic glycol, and monocarboxylic acid; and esterification or transesterification by adding a catalyst and a stabilizer into a mixture. The reaction product is manufactured through a polycondensation by adding a polycondensation reaction catalyst and a stabilizer. In chemical formula 1, n is an integer from 2-10, and R is a hydrogen or methyl group. |
