A series of novel polyamine resins were synthesized by the preparation of ketimine terminated resins from ketimine blocked diethylene triamine (I) and bisester derivative (II) of epoxy resin and subsequent hydrolysis. I was synthesized by the condensation reaction of diethylene triamine with methyl isobutyl ketone. II was synthesized by the reaction of epoxy resin (DGEBA) with amino ethyl benzoate (AEB). The hydrolysis of ketimine containing resin was evaluated by the change in pH value of the reaction mixture, and by infrared spectroscopy and Gel Permeation Chromatography of the resulting product. The thermal stability and coating properties of the synthesized polyamines were studied in some detail. The hydrolytic rate of ketimine increased with increase temperature or the amount of added acid. |
