Water-soluble polymers have been widely used in the oil and gas industry due to their unique properties such as ‎enhanced rheological properties and high thermal stability. Water-soluble acrylamide terpolymer nanocomposite ‎modified with hydrophilic groups of acrylic acid (AA) and hydrophobic groups of styrene (St) containing silica ‎nanoparticles was synthesized using one-step reverse-emulsion terpolymerization and its rheological properties ‎were studied. The structure of terpolymer silica nanoparticles was investigated using Fourier transform infrared ‎spectroscopy (FT-IR), and a field emission scanning electron microscopic analyze (FE-SEM), respectively. The ‎rheological investigation of solutions of the nanocomposite was studied using the rheometric mechanical spectrum ‎‎(RMS) and results showed that nanocomposite solutions have a shear-thinning behavior, and with increasing the ‎temperature the shear viscosities increase interestingly. Temperature resistance behavior of PAAS can be ‎ascribed to the presence of hydrophilic and hydrophobic blocks embodied in the polymer chain backbones that ‎form a three-dimensional network of polymer chains, including silica nanoparticles added via in-situ ‎polymerization.‎
