Abstract: A one component epoxy adhesive composition is comprised of an epoxy resin, a polyurethane based toughener, an epoxy capped toughener comprised of a polymer backbone capped with an epoxy, wherein the polymer backbone is at least partially immiscible in the epoxy resin; and an epoxy curing agent. The one component adhesive composition may have improved impact resistance at low temperatures, such as ?40° C. or less.

Abstract: A composition comprising a phase separated block copolymer and an inorganic dielectric nanoparticle, wherein the nanoparticle is dispersed in the copolymer and is present primarily in one phase. For example, a Ti02 nanocomposite can be created via the in situ formation of Ti02 within a silane-grafted OBC. Taking advantage of the phase morphology of the OBC and the differential swelling of the hard and soft segments, due to their inherent crystallinity, enables the selective incorporation of Ti02 nanoparticles into the soft segments of the OBC.
