Abstract: The invention relates to a foam layer which is produced from a biodegradable polyester mixture,comprising i) 70 to 5% by weight, based on the total weight of components i to ii, of at least one polyester made of aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds and ii) 30 to 95% by weight, based on the total weight of components i to ii, of polylactide, and iii) 0.1 to 5% by weight, based on the total weight of components i to ii, of an epoxy group-containing copolymer made of styrene, acrylic ester and/or methacrylic ester, and iv) 0.5 to 15% by weight of additives; and v) 0 to 50% by weight of inorganic or organic fillers. The invention also relates to methods for producing said foam layer and to the use of the foam layer for producing molded articles. It finally relates to films and molded parts and to films that contain the foam layers according to the invention.

Abstract: The present invention relates to aliphatic-aromatic polyesters comprising: i) 40 to 60 mol %, based on components i to ii, of one or more dicarboxylic acid derivatives selected from the group consisting of: sebacic acid, azelaic acid and brassylic acid; ii) 40 to 60 mol %, based on components i to ii, of a terephthalic acid derivative; iii) 98 to 102 mol %, based on components i to ii, of 1,3-propanediol or 1,4-butanediol and iv) 0.01 to 5 wt.-%, based on the total weight of components i to iii, of a chain extender and/or cross-linking agent selected from the group consisting of: a polyfunctional isocyanate, isocyanurate, oxazoline, carboxylic acid anhydride, epoxide and/or an at least trifunctional alcohol or an at least trifunctional carboxylic acid. The invention also relates to a method for manufacturing the polyesters, to polyester mixtures comprising said polyesters and to the use of said polyesters and polyester mixtures.

Abstract: The invention relates to foam layers which are produced from a biodegradable polyester mixture,comprising i) 30 to 10% by weight, based on the total weight of components i to ii, of at least one polyester made of aliphatic and aromatic dicarboxylic acids and aliphatic diols, containing ii) 70 to 90% by weight, based on the total weight of components i to ii, of polylactide, and iii) 0.5 to 3% by weight, based on the total weight of components i to ii, of a nucleating agent, iv) 0 to 10% by weight of additives; and v) 0 to 50% by weight of inorganic or organic fillers, the foam layer consisting of closed cells to more than 70% and having a density of less than 35 g/l. The invention also relates to methods for producing said foam layers and to the use of the foam layers for producing molded articles and films and to molded parts and films that contain the foam layers according to the invention.
