Abstract: 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 C4-C36 dicarboxylic acid or a mixture of a plurality of aliphatic C4-C36 dicarboxylic 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.

Abstract: The invention refers to a method for determining habitat descriptor values providing a target biodegradability for a polymer. A target biodegradability is provided indicative of a biodegradation characteristic of a polymer. A digital representation of a polymer indicative of physicochemical characteristics of the polymer is provided. A biodegradation habitat is provided indicative of habitat descriptors influencing a biodegradation of a polymer. A biodegradation model is provided based on the provided biodegradation habitat that is adapted to determine habitat descriptor values that allow for a biodegradation of the polymer meeting the target biodegradability in the biodegradation habitat. The habitat descriptor values are determined for the polymer based on the selected biodegradation model, the target biodegradability and the polymer descriptors.

Abstract: The invention refers to an apparatus (110) for predicting a technical application property for a polymer based on a digital representation of the polymer. A digital representation providing unit (111) provides a digital representation of the polymer indicative of polymer descriptors. The polymer descriptors are indicative of parameters quantifying physicochemical characteristics of subgroups of the polymer. A prediction model providing unit (112) provides a prediction model adapted to predict a technical application property of the polymer based on the digital representation, wherein the prediction model is a data-driven model parametrized such that it predicts based on the polymer descriptors indicated by the digital representation the technical application property associated with the polymer. A property determination unit (113) determines the technical application property based on the provided digital representation of the polymer and the prediction model. An output unit (114) provides the technical application property.
