| titleOfInvention | Aliphatic polyester copolymer and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide an aliphatic polyester copolymer excellent in biodegradability, having practically sufficient strength such as tensile strength, and excellent in moldability. SOLUTION: The present aliphatic polyester copolymer comprises: (A) aliphatic diols (ethylene glycol, 1,3- Propanediol, 1,4-butadiol, etc.) (B) an aliphatic dicarboxylic acid (succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, etc.), its acid anhydride or its diester compound, and (c) lactone (β-propio Lactone, γ-butyrolactone, δ-valerolactone, ε-caprolactone, etc.) or hydroxycarboxylic acid (glycolic acid, lactic acid, etc.) and are synthesized by polycondensation, and the ratio of the hydroxycarboxylic acid component in the product is 1 to 3. The weight average molecular weight Mw is in the range of 50,000 to 500,000, and the number average molecular weight Mn is in the range of 1,000 to 6,000. |
