Abstract

Biodegradable polyesteramides as defined in the specification are obtained by reacting a mixture consisting essentially ofa1) a mixture consisting essentially of35 to 95 mol % of adipic acid or ester-forming derivatives thereof,5 to 65 mol % of terephthalic acid or ester-forming derivatives thereof, and0 to 5 mol % of a compound containing sulfonate groups,a2) a mixture consisting essentially of95.5 to 0.5 mol % of a dihydroxy compound,0.5 to 99.5 mol % of an amino-C2-C12-alkanol or an amino-C5-C10-cycloalkanol,0 to 50 mol % of a diamino-C1-C8-alkane, and0 to 50 mol % of a 2,2′-bisoxazoline of the formula I  wherein R1 is as set forth in the specification, anda3) 0 to 5 mol %, based on a1), of a compound D as set forth in the specification;and other biodegradable polymers and thermoplastic molding compositions, their manufacture and their use for producing biodegradable moldings, adhesives, foams, and coatings.
