Abstract: The invention relates to biodegradable polyester mixtures comprising: between 5 and 80 wt. %, in relation to the total weight of the constituents i to ii, of at least one polyester based on aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds (constituent i); between 20 and 95 wt. %, in relation to the total weight of the constituents i to ii, of at least one renewable raw material (constituent ii); and between 0.1 and 15 wt. %, in relation to the total weight of the constituents i to ii, of a constituent iii that is suitable for forming covalent bonds both with constituent i and with constituent ii. The invention also relates to methods for producing biodegradable polyester mixtures, the use of biodegradable polyester mixtures for producing blends, moulded parts, films or fibres, in addition to blends, moulded parts, films or fibres comprising biodegradable polyester mixtures.
