Aqueous Solution Viscosity of Hydrophobically Modified Acrylamide Co- and Terpolymers Synthesized by Micellar Polymerization

Acrylamide/butyl acrylate (AM/BA) copolymer and AM/BA/2-acrylamido-2-methylpropane sulfonic acid (AM/BA/AMPS) terpolymer were synthesized in the presence of a low amount of hydrophobic monomer, i.e. BA, by micellar polymerization method where multi-block structure can be formed. Co- and terpolymer compositions were investigated by NMR spectroscopy. Rheological properties were investigated by viscosity measurement technique. Results showed that viscosity increases by increasing the polymer concentration. Polymer aqueous solution showed a shear thinning behavior. It was found that viscosity of the aqueous solution can significantly be affected by the polymer microstructure
