ABSTRACT:
Curable compositions comprising a curing agent and the product resulting from reacting (I) the product resulting from the free radical polymerization of (A) the composition resulting from (1) reacting (a) a compound containing an average of more than one vicinal epoxide group per molecule with (b) at least one unsaturated imide having a reactive hydrogen atom attached to the imide nitrogen atom in amounts which provide a ratio of moles of component (b) per epoxide group contained in component (a) of from about 0.01:1 to about 1.1:1; and (2) optionally, reacting the product of step (A) with (c) at least one of (i) at least one compound containing only one phenolic hydroxyl group, (ii) at least one secondary amine, or (iii) a combination of (i) and (ii) in amounts sufficient that the resulting product contains a percent epoxide value of not greater than about 1.5 percent by weight; and (B) a mixture of (d) at least one polymerizable monomer containing only one polymerizable ethylenically unsaturated group and only one carboxyl group per molecule (e) at least one polymerizable monomer containing only one polymerizable ethylenically unsaturated group per molecule and which is free of carboxyl groups; and (II) at least one of (f) at least one primary, secondary or tertiary amine; (g) at least one alkali metal hydroxide, alkali metal carbonate or alkali metal bicarbonate; or (h) any combination of (f) and (g); and wherein component (II) is present in an amount sufficient to render the resultant composition water miscible, water soluble or water dispersable.
