| titleOfInvention | Aliphatic polyester and process for producing the same |
| abstract | An object of the present invention is to provide an aliphatic polyester which is produced as a high-molecular-weight one without using a chain extender such as an isocyanate compound or a carbonate compound and is excellent in moldability in injection molding, blow molding, or extrusion molding, thermal stability, and mechanical properties such as tensile properties. n The invention relates to an aliphatic polyester comprising an aliphatic diol unit, an aliphatic dicarboxylic acid unit, and a unit of an organic acid having a pKa value of 3.7 or below at 25° C., wherein a content of a carbonate bond contained in the polyester is less than 1 mol %, a content of a urethane bond is less than 0.06 mol %, a content of an aliphatic monooxymonocarboxylic acid unit is less than 0.02 mol %, a content of the phosphorus atom derived from a phosphorus compound selected from among organic phosphinic acids, organic phosphonic acids, and hydrogen phosphate salts is less than 10 −9 mol %, based on the whole monomer units constituting the polyester, and a reduced viscosity (ηsp/C) is 1.6 or more. |
