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.

Abstract: A network polymer that contains:(a) a plurality of polymer chains which are derived from one or more ethylenically-unsaturated monomer(s), and(b) at least one linking group which links the polymer chains and which contains anhydride, carbonate, or uretidinedione moieties.The network polymer and other network polymers which contain similar dissociating groups are useful in curable formulations which contain a curable compound that contains:(a) a central moiety, and(b) a plurality of reactive groups which are bonded to the central moiety and which react with acid, hydroxyl, or isocyanate moieties liberated by dissociation of the anhydride, carbonate, or uretidinedione moieties.The curable composition builds viscosity more slowly and more controllably during curing than equivalent systems which do not contain the network polymer. It is useful in coatings and other uses for curable compositions.

Abstract: Strong base anion exchange resins that contain quaternary ammonium groups derived from higher molecular weight amines, such as triethylamine or tripropylamine instead of trimethylamine, have a higher reactivity for catalyzing the reaction of an epoxide compound with an acid compound to form an ester.

Abstract: The production of esters via the reaction of an epoxide with a carboxylic acid hasbeen shown to give improved activity when a strong base macroporous anion exchange resin having an acrylic backbone is used in place of a styrene-divinylbenzene based anion exchange resin having an equivalent exchange capacity. Excellent results are obtained when acrylic acid and propylene oxide are reacted together in the presence of strong base macroporous anion exchange resins which have an acrylic backbone.
