DEFINITION

Classification: 525/65

With saturated 1,2-epoxy reactant containing more than one 1,2-epoxy group per mole or polymer derived therefrom; or with solid copolymer derived from at least one unsaturated 1,2-epoxy reactant wherein the epoxy reactant contains more than one 1,2-epoxy group per mole and at least one saturated reactant:

(under subclass 64) Subject matter wherein, in addition to the solid graft or graft-type copolymer derived from ethylenic reactants only, there is also present (a) a saturated polyepoxide reactant or polymer thereof, or (b) a solid polymer derived from at least one saturated reactant and at least one unsaturated 1,2-epoxy reactant, e.g., a mixture of butadiene-styrene-acrylonitrile graft copolymer with trioxaneglycol diglycidyl ether copolymer, etc.

(1) Note. A saturated polyepoxide is by definition a specified polymer-forming ingredient; and see Class 520 Glossary for the definition of other terms noted as specified polymer-forming ingredients.
