Patent ID: 8871892

Claim:
An epoxy-functional oxazolidone resin composition comprising the reaction product of: (a) a divinylarene dioxide, (b) a polyisocyanate, and (c) a reaction catalyst; such that the reaction product formed is an epoxy-functional oxazolidone resin composition; wherein the reaction catalyst is selected from the group consisting of Lewis acids, imidazoles, quaternary salts, or mixtures thereof; wherein the epoxy-functional oxazolidone resin composition has an oxazolidone selectivity of greater than or equal to 70 percent relative to the total content of the carbonyl groups in the epoxy-functional oxazolidone resin composition; wherein the epoxy-functional oxazolidone resin composition has a viscosity of from about 0.1 Pa-s to about 10,000 Pa-s at 150° C.; wherein the epoxy-functional oxazolidone resin composition has a melt viscosity based on a ratio of T 500 :Tg of less than 1.5; wherein T 500 is the temperature at which the melt viscosity of the epoxy-functional oxazolidone resin composition is about 500 Pa-s; and wherein Tg is the glass transition temperature of the epoxy-functional oxazolidone resin composition.
