摘要： The present invention provides an aliphatic aromatic polyester 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) 60 to 40 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% by weight, based on the total weight of said components i to iii, of a chain extender and/or crosslinker selected from the group consisting of a polyfunctional isocyanate, isocyanurate, oxazoline, carboxylic anhydride, epoxide and/or an at least trihydric alcohol or an at least tribasic carboxylic acid. The present invention further provides a process for producing the polyesters, polyester blends comprising these polyesters and also for the use of these polyesters and polyester blends.
