Evidence for the existence of the ester form of the sulphate in unstabilized cellulose acetate has been examined by ion exchange studies on precipitated and fibrous cellulose acetate. The equilibrium reached during ion exchange is affected by the pH and by the concentration of the salt solution used. The thermal stability of the ester is shown to vary inversely with the sulphate content. A study has been made of the accuracy of the various analyses involved.

A series of resins was synthesized and analyzed for selective ion-exchange nature for some metals. Substituted aniline was reacted with formaldehyde, melamine. For the synthesis of ion-exchange resins, sulfuric acid was used as a catalyst. These resins were characterized by elemental analysis and studied antimicrobial activities. Synthesized Resin shows ion exchange capability and moderate activity against microbial. Ion exchange resin also showed reusability and stability at an elevated temperature.
