The relation between the quantity of adsorbed partially hydrolyzed polyacrylamide (HPAM) on two porous media and the hydrolysis degree( HD ) of HPAM was studied. The saturation adsorptions ( Ad ) of HPAM on the montmorillonite and the kaolinite decrease with increasing HD up to about 25%
and reach a minimum at about 25~30% HD
but increase with increasing HD if HD %>30%. This result could be explained by the formation of the maximum intramolecular hydrogen bonding of HPAM with the HD in the range of 15~30%.
