Abstract
EpB polyether alcohols were prepared by reacting 3,4-epoxy-1-butene with water or an alcohol such as methanol, butanol or ethylene glycol. Polyether alcohols thus prepared were found to have utility as reactive diluents for oxidatively curable coatings. In addition to this application, 3,4-epoxy-1-butene oligomers can also function as a resin, a chain extender, a monomer, and an additive for various oxidatively curable coating systems including alkyds, unsaturated polyesters, (meth)acrylate functional resins, urethanes, and latexes.
