Abstract: The present invention relates to a process for producing a (co)polyester, wherein the (co)polyester at least partially consists of 1,4-butylene dicarboxylate units, in a degassing plant, wherein the crude (co)polyester is degassed in the presence of 0.1% to 5% by weight, based on the total weight of the input materials, of an entraining agent at a pressure between 5 to 300 mbar.
