ABSTRACT Polymer modified adducts are prepared by (A) reacting (1) an epoxy resin having an average of more than one vicinal epoxide group with (2) a compound containing an average of two or more hydrogen atoms reactive with an epoxide group; and (B) partially vinylizing reacting the product from step (A); and (C) polymerizing the partially vinylized product from step (B) with (3) a polymerizable ethylenically unsaturated monomer; with the proviso that at least one of the components (1), (2) or (3) contain one or more mesogenic or rodlike moieties. These adducts are useful as epoxy resin curing agents. 38,742-F
