Abstract: iodegradable polyesters P1 obtainable by the reaction of a mixture consisting essentially of (a1) a mixture essentially of 35 to 95 mol% adipic acid or ester-forming derivatives thereof or mixtures thereof, 5 to 65 mol% terephthalic acid or ester-forming derivatives thereof or mixtures thereof, and 0 to 5 mol% of a sulphonate group-containing compound in which the sum of the individual mol percentages is 100, and (a2) a dihydroxy compound selected from the group consisting of C2-C6 alkane diols and C5-C10 cycloalkane diols, in which the molar ratio of (a1) and (a2) is in the range from 0.4:1 to 1.5:1, provided that the polyester P1 have a molecular weight (Mn) in the range from 5000 to 50,000 g/mol, a viscosity index in the range from 30 to 350 g/ml (measured in o-dichlorobenzole/phenol (in a ratio by weight of 50/50) at a concentration of 0.5 wt.% polyester P1 at a temperature of 25 C) and a melting point in the range from 50 to 170 C, and with the further proviso that from 0.01 to 5 mol% in relation to the molar quantity of the component (a1) used of compound D with at least three groups capable of forming esters are used to produce the polyesters P1, and other biodegradable polymers and thermoplastic moulding compounds and adhesives, biodegradable mouldings, foams and blends with starch obtainable from the polymers or moulding compounds of the invention.
