ABSTRACT:
The production of amine resins having Mannich base groups which dissolve in water with the aid of a solubilizing acid is disclosed in which a dihydric phenolic organic compound, such as a bisphenol, is reacted in organic solvent medium with at least 3 moles of formaldehyde per mol of bisphenol to at least partially methylolate the bisphenol prior to other reactions. The at least partially methylolated product is then reacted with a stoichiometric deficiency of organic diepoxide, and then with monosecondary amine to provide Mannich base groups. The Mannich base-containing product is then reacted with additional epoxide-functional material.
