    Abstract: The invention herein is a non-aqueous solvent free process for producing UV curable adhesive and sealant compositions comprising a tackifying resin and a monohydroxylated epoxidized polydiene polymer which is comprised of at least two polymerizable ethnically unsaturated hydrocarbon monomers wherein at least one is a diene monomer which yields unsaturation suitable for epoxidation and wherein the polymer contains from 0.1 to 7.0 milliequivalents of epoxy per gram of polymer. The process involves mixing the components with an insoluble photoinitiator under conditions of high shear and/or cavitation. The invention also relates to a film of 5 mils to one inch thick which is formed from the composition made according to the process above.

In a preferred embodiment, the polymer system is comprised of a hydroxyl functional telechelic diol or polyol polymer and the heterotelechelic polymer is a monohydroxylated polydiene polymer which also has epoxidized olefin functionality. The dual curing system preferably is comprised of an isocyanate curing agent to cure through the hydroxyl groups at ambient temperatures to form a pressure sensitive adhesive or sealant and an amino resin to cure through the epoxy functionality upon baking to form a structural adhesive or sealant.

    Abstract: 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.
