Investigation of Rheology Biocopolymer Based on Starch-poly(sodium acrylate-co-acrylamide)

摘要

In the present paper, attention is paid to investigates rheology of a superabsorbent hydrogel based on starch and polyacrylonitrile. The physical mixture of starch and polyacrylonitrile was hydrolyzed by NaOH solution to yield starch-poly(sodium acrylate-co-acrylamide) superabsorbent hydrogel, A proposed mechanism for hydrogel formation was suggested and the structure of the product was established using FTIR spectroscopy.
