Title: Polymeric quaternary ammonium hydroxides and their use in electrodeposition
Inventor: CHRISTENSON ROGER M
IPC: C08L63/00
Filed: 1977-06-30
Granted: 1981-08-25
Abstract: Abstract of the Disclosure Quaternary ammonium hydroxide-containing polymers and their use in cationic electrodeposition are disclosed. The quaternary ammonium hydroxide-containing polymers are particularly useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition. Upon electrodeposition, such resins generate acid which can build up to undesirable levels in the electrodeposition bath. The quaternary ammonium hydroxide-containing polymers are strong bases and when fed into the bath react with the acid to form the corresponding quaternary ammonium salt. This controls the pH of the bath at acceptable levels and provides additional cationic resin for electrodeposition. Utilizing the invention in this manner minimizes the need for controlling acid build-up in the electrodeposition bath by conventional techniques such as by treating the bath with ultrafiltration or electrodialysis. The quaternary ammonium hydroxide-containing polymers are also useful as electrodeposition resins themselves in that they electrodeposit without generating acid counter ion. Resinous compositions of the quaternary ammonium hydroxide-containing polymers in combination with curing agents are described as well as their use in coating applications such as cationic electrodeposition.
