<p>Polyethylenically unsaturated polyethers are produced by reacting a diepoxide with a stoichiometric proportion of a bisphenol to provide a phenolic OH terminated intermediate which is then reacted with a molar excess of ethylenically unsaturated monoepoxide. These polyethylenic polyethers are copolymerized with monoethylenic monomers in organic solvent solution to provide organic soluble copolymers.</p> |
