Water-soluble acrylamide-modified terpolymer nanocomposites modified with hydrophilic groups of maleic ‎anhydride and hydrophobic units of styrene, containing silica nanoparticles were synthesized using in-situ ‎polymerization and their rheological properties were studied. The formation of terpolymer and the incorporation ‎of silica nanoparticles into the structure of the terpolymer was studied by Fourier Transform Infrared ‎Spectroscopy (FT-IR) and the microstructure and size of the terpolymer and silica nanoparticles were ‎investigated by field emission scanning electron microscopy (FE-SEM). The rheological properties including ‎shear viscosity in different concentration of nanoparticle and different temperatures of the terpolymer solutions ‎and terpolymer containing silica nanoparticles solutions at different temperatures were studied using RMS ‎dynamic spectroscopy. The obtained results from RMS showed that the nanocomposites are resistance against ‎increasing temperature and by increasing the concentration of nanoparticles from 0.5 % wt. to 1.5 % wt., the ‎shear viscosities increase noticeably. These interesting temperature resistance behavior concludes that such ‎nanocomposites can practically be used in harsh conditions with high temperatures.‎
