Abstract: What are disclosed are polyesteramides prepared by the condensation of dimerized fatty acids having 16-44 carbon atoms with ethylene diamine and with aliphatic co-diamines which are optionally substituted and optionally interrupted by heteroatoms, with diglycolamine, and with aliphatic, cycloaliphatic, aromatic, or araliphatic co-dicarboxylic acids; mixtures of such polyesteramides with copolymers of ethylene and vinyl acetate; and methods for using these polyesteramides or mixtures for the adhesion of organic or inorganic substrates to themselves or to each other, or as sealing compounds.

Abstract: What are disclosed are a polyamide polymer and its use as a melt adhesive for adhering textiles, said polymer having a melt viscosity, measured at 220.degree. C., of 5-150 Pas and being the reaction product of approximately equivalent amounts of an acid component and a basic component, said acid component comprising(a) (1) a dimerized fatty acid having a content of 70-100 percent by weight of dimeric fatty acid and, optionally,(a) (2) a monocarboxylic acid, as a molecular weight regulator, having up to 22 carbon atoms, which monocarboxylic acid may be present in an amount up to 50 equivalent percent of the total carboxy groups of the mixture (a) (1) and (a) (2);(b) at least one aliphatic straight chain co-dicarboxylic acid having 6 to 13 carbon atoms, wherein the ratio of carboxylic acid according to (a) (1) and (a) (2) to carboxylic acid according to (b) is from 0.
