Abstract (en)

[origin: DE19800698A1] The invention relates to block-shaped polyester amides with an amide or ester structure, containing the following monomers: aliphatic dialcohols or cycloaliphatic diols and/or aliphatic dicarboxylic acid also in the form of a corresponding ester and/or aromatic dicarboxylic acids also in the from of a corresponding ester and/or hydroxy carboxylic acids and lactone and/or amino alcohols and/or cyclic lactames, and/or omega amino carboxylic acids and/or mixtures (1:1 salts) of dicarboxylic acids and diamines, whereby the polyester amides can be obtained by polycondensation of a hydroxy, acid or ester terminated ester block and an amino acid or ester terminated amide block, whereby the ester content of the polyester amide is 20-80 wt. % and the amide content is 80-20 %.
