    Abstract: Novel thermoplastic adhesive components, prepared from inexpensive and readily available synthetic materials, having melting points between about 20.degree. C. to about 180.degree. C. and broad ranges of hardness, flexibility and compatibility are disclosed. The novel thermoplastic compounds useful in adhesive formulations are comprised of a resinous polyamide reaction product of a polyoxypropylene polyamine having an average molecular weight of from about 190 to about 3,000 and being selected from diamines, triamines, or mixtures thereof, piperazine and an aliphatic or aromatic dicarboxylic acid, ester or anhydride having from about 4 to about 20 carbon atoms per molecule. The resinous polyamide reaction product is prepared by mixing and reacting the polyoxypropylene polyamine, piperazine, and dicarboxylic acid materials in a total amine:acid molar ratio within the range of from about 0.25:1.0 to about 4.0:1.0 at a temperature of from about 175.degree. C. to about 270.degree. C. The inventive thermoplastic polyamides can be formulated with compatible plasticizing agents to prepare a useful adhesive to which can also be added other components, such as a minor amount of a polyepoxide resin having an epoxide equivalent weight of about 150 to about 600, fillers and the like to produce thermoplastic adhesive formulations having desired hardness, flexibility and compatibility that are capable of bonding together a variety of substrates.

    Abstract: The adhesion properties of amine-cured epoxy resins are unexpectedly enhanced by addition of certain di-hydroxyalkyl carbamate terminated polyether additives. The adhesively superior epoxy resin composition comprises a vicinal polyepoxide, a curing amount of an amine curing agent, and an effective amount of a polyether dicarbamate having terminal hydroxyalkyl carbamate groups and a molecular weight of from about 2000 to about 3000.
