Abstract: The invention concerns biologically degradable polyether ester amides P1 obtainable through reaction of a mixture consisting essentially of the following: (a1) a mixture consisting essentially of: 20-95 mol % adipic acid or ester-forming derivatives thereof or mixtures thereof, 5-80 mol % terephthalic acid or ester-forming derivatives thereof or mixtures thereof; 0.5 mol % of a compound containing sulphonate groups, the sum of the molar percentages being 100; (a2) a mixture of dihydroxy compounds consisting essentially of: (a21) 15-99,3 mol % of a dihydroxy compound chosen from the group comprising C2-C6 alkane diols and C5-C10 cycloalkane diols; (a22) 0.2-85 mol % of a dihydroxy compound containing ether functions, determined by formula I HO-[(CH2)n-O]m-H, wherein n is 2, 3 or 4 and m is an integer between 2 and 250, or mixtures thereof; (a23) 0.5-80 mol % of an amino-C2-C12 alkanol or an amino C5-C10 cycloalkanol; and (a24) 0-50 mol % of a diamino C1-C8 alkane; (a25) 0-50 mol % of a 2,2'-bisoxazoline. 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 made from the polymers or moulding materials according to the invention.
