摘要
Hydrophobically associating polyacrylamides(HAPAMs) were copolymerized with hydrophilic comonomers acrylamide,sodium acrylic acid a surfactive hydrophobe capable of polymerizing,cetyl dimethyl allyl ammonium chloride,and the effects of polymer concentration,salt and shear rate on HAPAMs’ apparent viscosity have also been investigated.The results reveal that HAPAMs have advantages in viscosifying ability and salt resistance over conventional polyacrylamide(PAM) and have a comparable shear thinning ability with PAM.
