The polyester amides P1 will have a molecular weight (Mn) in the range 4000-40,000 g/mol, a viscosity number in the range 30-350 g/ml (measured in o-dichlorobenzene/phenol (weight ratio 50/50) at a concentration of 0.5 wt.% polyester amide P1 at a temperature of 25 ~C) and a melting point in the range 50-220 ~C; and a quantity of a compound D equivalent to 0-5 mol % of the molar quantity of components (a1) must also be used for the production of the polyester amides P1, said compound D having at least three groups capable of ester formation. The invention also concerns other biologically degradable polymers and thermoplastic moulding materials, processes for manufacturing the same, the use thereof for producing biologically degradable moulded articles and adhesives, and biologically degradable moulded articles, foams and blends with starch which can be obtained from the polymers or moulding materials according to the invention.
