AN EFFECTIVE METHOD TO IMPROVE THE WET STRENGTH OF POLY(DIALLYLDIMETHYL-AMMONIUM CHLORIDE)HYDROGELS

摘要

New IPN hydrogels composed of diallyldimethylammonium chloride (DADMAC) and natural macromolecule,kappa-carrageenan (KC) were prepared by gamma irradiation and their properties were studied. The results show that both the gel strength and the swelling capacity of the IPN hydrogels were enhanced significantly as compared with those of the pure hydrogels of PDADMAC.
