Abstract: The invention refers to a method for determining a synthesis specification comprising a target biodegradability. A target biodegradability is provided indicative of a biodegradation characteristic of a polymer. A digital representation of a potential target synthesis specification is provided indicative of physicochemical characteristics of the polymer. A habitat is provided indicative of habitat descriptor values of habitat descriptors. A model is provided based on the habitat that is adapted to determine the biodegradability of a polymer in the habitat. The biodegradability of the potential target polymer is determined based on the provided model and the digital representation. Then the determined biodegradability is compared with the target biodegradability and either i) the potential target polymer is determined as the target polymer, or ii) a new potential target synthesis specification of a potential target polymer is provided and the determination of the biodegradability is repeated utilizing the new potential target synthesis specification.

Abstract: The present invention relates to a biodegradable lamination film having the A/B layer structure, where layer A of thickness 0.5 to 7 μm comprises a polyurethane or acrylate adhesive; and where layer B of thickness 5 to 150 μm comprises an aliphatic polyester and/or aliphatic-aromatic polyester, where the aliphatic-aromatic polyester is of the following composition: b1-i) 30 to 70 mol %, based on components b1-i and b1-ii, of a C6-C18 dicarboxylic acid; b1-ii) 30 to 70 mol %, based on components b1-i and b1-ii, of terephthalic acid; b1-iii) 98 to 100 mol %, based on components b1-i and b1-ii, of propane-1,3-diol or butane-1,4-diol; b1-iv) 0% to 2% by weight, based on components b1-i and b1-iii, of a chain extender and/or branching agent.

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.
