DEFINITION

Classification: 525/113

With nitrogen-containing reactant, or wherein the poly 1, 2-epoxy reactant contains a nitrogen atom:

(under subclass 107) Subject matter wherein there is, in addition, a nitrogen- containing reactant which can be added at any time to the solid polymer from ethylenic reactants only; or wherein the reactant which contains more than one 1, 2- epoxy group per mole contains nitrogen, e.g., a mixture of poly (styrene-acrylic acid), poly (epichlorohydrin-bisphenol A) and ethylene diamine.
