    • A curable divinylarene dioxide resin composition having a stoichiometric excess of divinylarene dioxides cured with amines, anhydrides, or polyphenols. The curable divinylarene dioxide resin composition includes (a) a stoichiometric excess of at least one divinylarene dioxide, (b) a co-reactive curing agent, and a catalyst. A process for making the above curable divinylarene dioxide resin composition; and a cured divinylarene dioxide resin composition made therefrom are also disclosed. The curable divinylarene dioxide resin composition has a longer pot life prior to cure and produces a thermoset having a higher heat resistance after cure than analogous prior art compositions made using stoichiometric compositions. The curable compositions of the present invention are advantageously useful as thermoset materials, coatings, composites, and adhesives.
    • 用胺,酸酐或多酚固化的化学计量过量二乙烯基芳烃二氧化物的可固化二乙烯基芳烃二氧化物树脂组合物。 可固化的二乙烯基芳烃二氧化物树脂组合物包括(a)化学计量过量的至少一种二乙烯基芳烃二氧化物,(b)共反应性固化剂和催化剂。 制备上述可固化二乙烯基芳烃二氧化物树脂组合物的方法; 还公开了由其制成的固化二乙烯基芳烃二氧化物树脂组合物。 可固化的二乙烯基芳烃二氧化物树脂组合物在固化之前具有较长的适用期,并且产生具有比使用化学计量组合物制备的现有技术组合物的固化后更高的耐热性的热固性材料。 本发明的可固化组合物有利地用作热固性材料,涂料,复合材料和粘合剂。

    • An epoxy oxazolidone including the reaction product of (a) a divinylarene dioxide, and (b) an excess of a polyisocyanate to provide an epoxy oxazolidone composition; wherein the composition has an oxazolidone selectivity of greater than 40 % relative to the total of the carbonyl compounds; a process for making the epoxy oxazolidone; and a curable epoxy resin composition including (i) the epoxy oxazolidone derived from a divinylarene dioxide such as divinylbenzene dioxide (DVBDO) and a polyisocyanate, (ii) at least one curing agent; and/or (iii) a catalyst. The cured product made from the above epoxy resin composition is thermally stable and offers improved properties such as a lower viscosity and a high heat resistance compared to known cured products prepared from known epoxy resins.
