Abstract: A process for making an aromatic glycidyl ether epoxy compound by contacting an allyl ether made from the hydroxy moiety of a hydroxy-containing aromatic compound with an inorganic or organic hydroperoxide oxidant in the presence of a transition metal complex catalyst, wherein at least (a) the allyl ether is conformationally restricted or (b) the transition metal complex catalyst contains at least one or more stable ligands attached to the transition metal. The process of the present invention provides for epoxidizing aryl allyl ethers with high epoxidation yield (for example, greater than 70% to 90%) and high hydroperoxide selectivity (for example, greater than 70% to 90%).

Abstract: A process reaction between: (1) a compound that contains one or more epoxide moieties per molecule, and (2) a compound that contains one or more primary aliphatic hydroxyl groups per molecule; is catalyzed by: (3) a catalyst compound containing one or more trifluoromethanesulfonate moieties and one or more silyl moieties and run at a temperature of no more than 130.degree. C., such that the catalyst preferably catalyzes reaction at the primary aliphatic hydroxyl group, so that the resulting resin does not gel.

Abstract: Graft copolymers containing:(1) a phenolic resin; and(2) a poly(alkylene oxide) chain pendant to the phenolic resin,selected such that the graft copolymer has a solubility of no more than about 10 g/L in water, are taught. The graft copolymers are useful in coatings compositions with a curing agent, a solvent, and optionally an epoxy resin. The curable compositions have improved flexibility and/or solvent resistance. They are particularly useful in can coatings.
