Studies on grafting in a polymer by thermal analysis


Author(s): Aloke Chattopadhyay

Abstract: Guargum-graft-acrylamide (G-g-Am) is a modified natural polymer and has considerable biodegradation resistance and is an efficient flocculent for metallic ions. G-g-Am can be prepared by ceric ion initiation method. Evidence of grafting may be obtained rheologically by study of apparent viscosities. But thermal analysis may be an alternate method to understand possibility of grafting. In this investigation, DSC plots for G-g-Am and polyacrylamide are compared and DTA plot for industrial polyacrylamide is studied to understand difference in product formed near about 223 0C which indicates possibility of presence of graft in G-g-Am obtained by ceric ion initiation method.
