Abstract: The present invention relates to a process for producing aqueous dispersions of thermoplastic polymers which have a multitude of ester groups and/or carbonate groups in the polymer backbone, and which have an acid number of less than 5 mg KOH/g, especially not more than 3 mg KOH/g, and a zero-shear viscosity ?0 (180°C) at 180°C of at least 60 Pa·s. The invention also relates to polymer dispersions obtainable by this process and to the use thereof.

Abstract: The invention relates to a foam ply based on a biodegradable polyester mixture, comprising i) from 70 to 5% by weight, based on the total weight of components i to ii, of at least one polyester based on aliphatic and aromatic dicarboxylic acids and on aliphatic dihydroxy compounds, and ii) from 30 to 95% by weight, based on the total weight of components i to ii, of poly-lactide, and iii) from 0.1 to 5% by weight, based on the total weight of components i to ii, of a copolymer which comprises epoxy groups and is based on styrene, acrylates, and/or methacrylates, and iv) from 0.5 to 15% by weight of additives; and v) from 0 to 50% by weight of inorganic or organic filler, and also to processes for production of the foam ply mentioned, and to the use of the foam plies for the production of moldings and foils, and also to moldings and foils comprising the foam plies mentioned.
