Abstract: The invention relates to a biodegradable copolyester that has a molecular weight Mn measured in accordance with GPC of 10,000 to 100,000 and that can be obtained by reacting vi) 51 to 84 wt%, with respect to the copolyester, of a branched polyester middle block based on aliphatic or aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds and having a molecular weight Mn measured in accordance with
1 H-NMR of 5,000 to 25,000 with vii) 15.9 to 48.9 wt%, with respect to the copolyester, of a lactide in the presence of a catalyst and then reacting the polyester triblock thus obtained and having a molecular weight Mn measured in accordance with
1 H-NMR of 5,800 to 49,500 with viii) 0.1 to 3 wt%, with respect to the copolyester, of a diisocyanate. The invention further relates to a method for producing the biodegradable copolyesters mentioned above and to the use of the biodegradable copolyesters mentioned above.
