| titleOfInvention | Continuous method for producing an aliphatic polyester |
| abstract | The invention relates to a continuous method for producing an aliphatic polyester, made of aliphatic dicarboxylic acids and aliphatic diols, having the stages of a) esterification, b) polycondensation, and optionally c) chain extension. The invention is characterized in that the raw polyester is degassed in the presence of 1 to 7 wt.%, based on the total weight of the raw polyester, of water as an entraining agent supplied to the gas chamber of the degassing system B and/or B' at a pressure of 0.01 to 5 mbar during the stage b) in which the polycondenser functions as a degassing system (B) and/or b') after the polycondensation process in an additional degassing system (B'). |
