Hydrophobically Associating

The effects of Na+, Ca2+, and Mg2+ on hydrophobically associating water-soluble polymers (HAWP) were studied in this paper.Their decreased viscosity in aqueous solution at different salt concentrations were measured and the corresponding microstructure by Atomic Force Microscopy (AFM) were determined. The results show that the destructive microstrucure was the intrinsic reason for the decresed viscosity. Among the three salt aqueous solutins, CaCl2 has the highest strong destructive capability to the microstucute of HAWP.

Small-angle neutron scattering is used to measure the number of bound water molecules associating with three polymers over a wide concentration range. Different fitting workflows are evaluated and recommended depending on the concentration regime.
