AMORPHOUS AND/OR SEMICRYSTALLINE COPOLYESTERS CONTAINING .BETA.-HYDROXYALKYLAMIDE GROUPS, METHOD FOR THEIR MANUFACTURE, AND UTILIZATION OF THE ESTERS

摘要

Amorphous and/or semicrystalline copolyesters containing .beta.-hydroxyalkylamide groups according to formula (I). (see formula I) wherein P = polymer chain of the polyester R1 = alkyl residues with 1-5 C-atoms or hydrogen or (see formula II) R2 = alkyl residues with 1-5 C-atoms or hydrogen, R3 = alkyl residues and 1-5 C-atoms or hydrogen, and n .gtoreq. 2, with a molecular weight (Mn) of 300 to 15'000 and a hydroxyl value of 10 to 400 [mg KOH/g].
