Abstract: The invention concerns biologically degradable polyether ester amides Q1 with a molecular weight (Mn) in the range 6000-8000 g/mol, a viscosity number in the range 30-450 g/ml (measured in o-dichlorobenzene/phenol (weight ratio 50/50) at a concentration of 0.5 wt.% polyether ester amide Q1 at a temperature of 25 DEG C) and a melting point in the range 50-200 DEG C, obtainable through reaction of a mixture consisting essentially of the following: (a1) 95-99.9 wt.% polyether ester amide P1 with a molecular weight (Mn) in the range 6000-80,000 g/mol, a viscosity number in the range 30-450 g/ml (measured in o-dichlorobenzene/phenol (weight ratio 50/50) at a concentration of 0.5 wt.% polyether ester amide P1 at a temperature of 25 DEG C) and a melting point in the range 50-200 DEG C, obtainable through reaction of a mixture consisting essentially of: (b1) 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; and 0-5 mol % a compound containing sulphonate groups (the sum of the molar percentages is 100); (b2) a mixture of dihydroxy compounds consisting essentially of: (b21) 15-99.3 mol % a dihydroxy compound chosen from the group comprising C2-C6 alkane diols and C5-C10 cycloalkane diols; (b22) 0.2-85 mol % a dihydroxy compound containing ether functions, of 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; (b23) 0.5-80 mol % an amino-C2-C12 alkanol or an amino C5-C10 cycloalkanol; and (b24) 0-50 mol % a diamino C1-C8 alkane; (b25) 0-50 mol % a 2,2`-bisoxazoline of general formula II, in which R is a single bond, a (CH2)q-alkylene group in which q = 2, 3 or 4, or a phenylene group (the sum of the individual molar percentages is 100 and the selected molar ratio of b1 to b2 is in the range 0.4:1 - 1.5:1; (a2) 0.1-5 wt.% a divinyl ether C1; and (a3) 0-5 mol % (in relation to components b1 from the production of P1) compound D. The invention also concerns other biologically degradable polymers and thermoplastic moulding materials, processes for manufacturing the same and the use thereof for producing biologically degradable moulded articles and adhesives, and biologically degradable moulded articles, foams and blends with starch obtainable from the polymers or moulding materials according to the invention.
