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.

Method for preparing a (co)polyester

The present disclosure is related to a surfactant comprising at least one C8 to C30 branched alkanol alkoxylate, a process for the preparation of the surfactant, an article comprising the surfactant, and a use of the surfactant. Also disclosed are readily biodegradable surfactants obtained from branched aliphatic alcohols and including a polyethylene oxide block.

Biodegradable surfactant

The present invention relates to a polyester consisting of (A) repeat units derived from an acid component, which consists of (a1) 2,5-furandicarboxylic acid, (a2) an aliphatic C-Cdicarboxylic acid or a mixture of a plurality of aliphatic C-Cdicarboxylic acids, and (a3) a sulfonate group-containing dicarboxylic acid, and of (B) repeat units derived from a di-ol/amine component, and optionally of further repeat units (C) and/or branching components (E), and of (D) repeat units derived from at least one di- or oligofunctional compound selected from the group consisting of a di- or oligoisocyanate and a di- or oligoisocyanurate. In addition, the present invention relates to the production of these polyesters and their use.
