Abstract
Quaternary ammonium hydroxide-containing polymers and their use in coating applications are disclosed. The quaternary ammonium hydroxide-containing polymers are prepared from reacting a polyglycidyl ether of a cyclic polyol with a tertiary amine in the presence of a sufficient amount of water for the formation of quaternary hydroxide groups. The quaternary ammonium hydroxide-containing polymers are particularly good as electrocoating resins in that they electrodeposit without generating acid counterion. They are also good in other conventional coating applications such as dip, flow, spray and roll coating in that the resulting coating can be baked without the generation of corrosive acid.
