    • This invention relates to two-component curable hot-melt compositions comprising thermoplastic polyamide resins that are substantially free of piperazine-containing polyamines. In one preferred embodiment the polyamide resins are the reaction product of an acid component with an amine component, wherein the amine component consists essentially of about (i) 20 to 100 equivalent percent of one or more acyclic diamines selected from the group consisting of 2-methyl-1,5-pentanediamine, 1,3-pentanediamine, 1,3-propanediamine, 1,5-pentanediamine, 1,7-heptanediamine, 1,9-nonanediamine, methyl-1,9-nonanediamine, 1,2-propanediamine, and 2-methyl-1,2-diaminopropane, and (ii) about 0 to 80 equivalent percent of one or more polyamines selected from the group consisting of cyclic and acyclic polyamines other than those amines of (i). The compositions possess excellent heat resistance, flexibility, elasticity and resistance to solvents, including organic solvents and water.

    • There is disclosed a group of poly(ester-amide) compositions which possess unexpectedly good low temperature adhesive properties with respect to vinyl based substrates. These poly(ester-amide) compositions are the reaction product of a polymeric fatty acid, with an organic diamine, dicarboxylic acid and an alkanolamine having the general formula: ##STR1## wherein R.sub.2 represents alkylene of 2 to 8 carbons, and R.sub.1 is selected from the group consisting of hydrogen and a monovalent moiety of the formula:R.sub.3 --CH.sub.2 --CH.sub.2 -- (II)wherein R.sub.3 is selected from hydroxyl and amino groups.The term "alkylene of 2 to 8 carbons" as used throughout the specification and claims means a divalent moiety of the formula:--CH.sub.2 --CH.sub.2).sub.n CH.sub.2 -- (III)wherein n is an integer of from 0 to 6. N-(2-hydroxyethyl)piperazine is a preferred compound of the alkanolamine group.
