Abstract
A method for producing sucrose-based epoxy monomers having one to eight epoxy groups per molecule of sucrose, which comprises reacting a mixture comprising: a sucrose monomer having an allyl-containing group on at least one of the hydroxyl groups, and a reagent or catalyst selected from molybdenum, tungsten, vanadium, titanium and peracid, in the presence of hydrogen peroxide or a derivative thereof, in relative amounts sufficient to produce a sucrose-based epoxy monomer. Monomers thus produced are also provided. The sucrose-based epoxy monomers can be cured to produce a sucrose-based epoxy resin. Such resins are useful, for example, as adhesives, composites and coatings.
