Abstract
Hydrophobically modified polyacrylamide (HMPAM) is extensively used, although it is still challenging high salinity in practical applications. In this research, hydrophobically modified polymers (SPC16 and SPC18) with different hydrophobic monomers concentrations were synthesized by a free radical polymerization. The effect of sodium hydroxide on apparent viscosity. The viscometer was used for the apparent viscosity measurements. The methods based on β-cyclodextrin inclusion involved to quantitatively evaluate the contribution of self-association of polymer molecular to apparent viscosity. Using NaOH of 1 wt. % and changing the concentration of hydrophobic monomers from 0.02 to 0.2 wt% for SPC18 and the inclusion of β-cyclodextrin. While for SPC16, 0.1, and 0.05% of the hydrophobic concentration with different concentrations of β-cyclodextrin from 0 to 1.0 wt. % were analyzed. The amphiphilic polymers with the highest hydrophobic monomers has the highest viscosity. But, upon increasing the β-cyclodextrin from 0.1 to 1.0 wt. %, the polymers with low hydrophobic monomers concentrations viscosities decreased to the minimum value compare to the amphiphilic polymers with high concentration of hydrophobic monomers.
