Abstract

Polyamine resins were synthesized by the preparation of ketimine‐terminated resins from epoxy resin and ketimine blocked diethylene triamine (1) and subsequent hydrolysis. 1 was prepared by the condensation reaction of diethylene triamine with methyl isobutyl ketone catalyzed by acid. The hydrolysis of ketimine containing resin was evaluated by the change of the pH value of reaction mixture and the infrared spectroscopy and gel permeation chromatography curve of the resulting product. The hydrolytic rate of ketimine increased with the increase of temperature or the amount of acid added. The crosslinking, emulsion, and electrodeposition properties of these polyamine resins were studied in some detail.
