Studies on grafting in a polymer by using roto viscometer

Abstract

Guargum is a water soluble natural polymer and has good industrial use. But aqueous solution of guargum has poor biodegradation resistance. To improve biodegradation resistance, polyacrylamide side chains may be grafted on guargum to get guargum-graft-acrylamide. Characterization of polymer sample has been done by ESCA study and by thermal analysis. This present work is based in rheological study and it indicates presence of large number of grafted sites in a molecule of the polymer.
