Abstract
Epoxy-free hydroxy functional polyethers are provided which are the reaction product of a diglycidyl ether of a bisphenol having a molecular weight of about 1000 with a stoichiometric proportion of oleyl alcohol. These oleyl alcohol-based polyethers can be copolymerized in organic solvent solution with monoethylenically unsaturated monomers to form solvent-soluble copolymers. When the monomers include carboxyl-functional monomers providing an acid number in the range of 12-60, the copolymers are particularly adapted to be dispersed in water with the aid of a base and then electrodeposited at the anode together with a heat-hardening formaldehyde condensate to form corrosion resistant coatings.
