| titleOfInvention | Continuous method for producing an aliphatic polyester |
| abstract | The invention relates to a continuous process for producing an aliphatic polyester constructed from aliphatic dicarboxylic acids and aliphatic diols comprising the steps of a) esterification, b) polycondensation and optionally c) chain extension, characterized in that during step b) in which the polycondenser functions as a degassing apparatus (B) and/or b′) after the polycondensation in an additional degassing apparatus (B′) the crude polyester is degassed at a pressure of 0.01 to 5 mbar in the presence of 1% to 7% by weight, based on the total weight of the crude polyester of water, introduced into the gas space of the degassing apparatus B and/or B′ as an entraining agent. |
