Abstract:

The relationship among apparent viscosity, concentration and shear thinning behavior of ANPE-HAWP solution, as well as ability of resisting temperature and salt are studied. The experimental results indicate that ANPE-HAWP solution have obvious critical associating concentration（CAC ) and its ability of temperature tolerance and salt resistance is quite different from sample of reference P(AMPS-AM). Apparent viscosity at different shear rate shows that solution structure of ANPEHAWP can swiftly reversible restore. CAC of different type of HAWP are determined and experimental results verify the new HAWP molecular design idea of high-ratio inter-molecular association.

Key words: solution properties, temperature tolerance, salt resistance, shear thinning behavior, critical associating concentration (CAC), polymer
