Abstract

Hydrogels of Carboxymethyl Cellulose Crosslinked with Irradiation at Dilute and Paste-Like Condition

Author(s): S. Sultana, M. Rabiul Islam and M. E. Haque

Polysaccharides such as cellulose, starch and their water-soluble polymer derivatives have been known as degradable type polymers under action of ionizing radiation. Recently, we found that watersoluble polysaccharides derivatives such as carboxymethyl cellulose (CMC) lead to radiation cross-linking at high concentrated aqueous solution (more than 10%, paste-like state). It was proved that the crosslinking was remarkably affected by their concentration. It was assumed that radiation formation of hydrogels of these polysaccharides derivatives were mainly due to the mobility of side chains. Side chains radicals were formed mostly via indirect effects, by the abstraction of H atoms by the intermediate products of water radiolysis. Some important characteristics of these prepared hydrogels were investigated.
