Abstract:
A polyether ester amide which has a random arrangement of ester and amide segments wherein alcohol component consists ofa) at least one oligomeric diol selected from the group consisting of polyethylene glycols, polypropylene glycols, polyglycols composed randomly or in block-like manner from mixtures of ethylene oxide or propylene oxide, and polytetrahydrofurans with weight average molecular weight of between 100 and 10,000 andb) at least one monomeric diol selected from the group consisting of C2-C12-alkyl diols, and wherein acid component consists ofc) one or more monomers selected from the group consisting of C2-C12-alkyl dicarboxylic acids, C2-C12-alkyl hydroxycarboxylic acids, amino alcohols with 2 to 12 C atoms in the alkyl chain, cyclic lactams with 5 to 12 C atoms, -aminocarboxylic acids with 6 to 12 C atoms, and salts of a 1:1 mixture of C2-C12-alkyl dicarboxylic acids and C2-C12-dialkyl amines.
