Reaction of a diepoxide with a mono-, or, preferably, dicarboxylic acid yields a prepolymer having both hydroxy and epoxy groups. This prepolymer, when reacted with a polyisocyanate, yields a poly(oxazolidone/urethane) thermoset composition which is substantially free of isocyanurate linkages. The thermoset contains oxazolidone linkages in its backbone which are separated from one another by ester linkages. Urethane linkages are present in side chains attached to the polymer backbone of the thermoset.

Isocyanate-reactive prepolymers containing at least one terminal epoxide group with an associated secondary hydroxy group and grafted thereto a polymeric moiety derived from polymerizing an ethylenically unsaturated monomer are disclosed. When reacted with isocyanate, these prepolymers form thermoset compositions which comprise oxazolidone groups in the backbone that are separated by ester linkages, urethane linkages in side chains attached to the backbone, and polymeric moieties derived from one or more ethylenically unsaturated monomer grafted to the polymer backbone.

Reaction of a polyol, acid anhydride and diepoxide, preferably in a single step, yields a prepolymer composition containing a prepolymer containing terminal epoxy and non-terminal, secondary hydroxy groups. Reaction of this prepolymer with a polyisocyanate yields a poly(oxazolidone/urethane) thermoset composition which is essentially free of isocyanurate linkages. The thermoset contains oxazolidone linkages in the backbone of its recurring unit and urethane linkages which are present in a side chain of the unit.

Adhesive compositions are disclosed which comprise: (a) an epoxy resin; (b) a soluble polyimide resin; and (c) a monoepoxy diluent. Such compositions are curable by using conventional epoxy curing agent(s). If desired, conductive adhesives of this type can be formed by blending the composition with a conductive filler component.
