ABSTRACT:
This invention relates to products formed by reacting an aqueous solution of chromium trioxide with fluid reactive polyamide resins that are useful and novel as co-reactants or curing agents for epoxy resins, having characteristics of accelerating the curing rate, of increasing the toughness of the cured product, and of providing intrinsic or self-contained corrosion-inhibiting properties.
The reactive polyamide resins are identified as condensation products of polyfunctional polyalkylamines and a polyene fatty acid to form higher molecular weight materials which contain both aliphatic amine and amide functional groups.
