Abstract

Hydrophobically modified polyacrylamides were synthesized by the micellar copolymerization of acrylamide, 3-[N-(2-methacryloxyethyl)-N,N-dimethylamino]propane sulfonate and di-n-octylmethacrylamide using 2,2'-azobis(2-methylpropionamidine)dihydrochloride as the initiator. The structure, composition, molecular weight of copolymers were studied via 1H NMR, element analyse and static light scattering. Their thermal properties and aggregation properties of the copolymers were investigated by thermogravimetric analyzer, fluorescence spectroscopy, dynamic light scattering and surface tension. Thermal degradation and viscosity stability showed that hydrophobically modified polyacrylamide can greatly improve salt resistance and thermal stability and it has the high practical application performance in oil recovery.
