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 present invention relates to a process for increasing the hydrolysis resistance of biodegradable polyesters based on aliphatic or aliphatic and aromatic dicarboxylic acids and on aliphatic dihydroxy compounds, or a mixture of these polyesters, characterized in that from 0.1 to 5% by weight of a copolymer containing epoxy groups and based on styrene, acrylate and/or methacrylate is admixed in the extruder at from 160 to 260°C with the biodegradable polyester. It further relates to a process for increasing melt viscosity and to a process for increasing the stability of the melt of biodegradable polyesters under shear.
