摘要

The invention concerns biologically degradable polyester amides Q1 obtainable through reaction of a mixture consisting essentially of the following: (a1) 95-99.9 wt % polyester amide P1 obtainable through reaction of a mixture consisting essentially of: (b1) a mixture consisting essentially of: 35-95 mol % adipic acid or ester-forming derivatives thereof or mixtures thereof, 5-65 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) 99.5-0.5 mol % a dihydroxy compound chosen from the group comprising C2-C6 alkane diols and C5-C10 cycloalkane diols, (b22) 0.5-99.5 mol % an amino C2-C12 alkanol or an amino C5-C10 cycloalkanol, (b23) 0-50 mol a diamino C1-C8 alkane, and (b24) 0-50 mol % a 2,2´-bisoxazoline; (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, a process for manufacturing the same and the use thereof for producing biologically degradable moulded articles and adhesives, and biologically degradable moulded articles obtainable from the polymers or moulding materials according to the invention.
