چکیده
The copolymer of acrylamide (AM) and 2-acrylamido-2-methyl-1-propane sulfonate (AMPS) was synthesized through the radical solution polymerization using potassium persulphate as initiator. By changing the AMPS feed ratio from 10 to 70%, and keeping other reaction conditions constant,different copolymers were synthesized. The techniques of Fourier transform infrared (FTIR) and nuclear magnetic resonance (1H- 13 C-NMR) spectroscopy were used as tools for the identification of functional groups and the confirmation of the structure of the copolymers obtained. Intrinsicviscosity and appearance viscosity of sample was measured in aqueous sodium chloride solution under standard conditions. The anionic degree of copolymers was determined by back titration method and by 13C-NMR spectroscopy. Molecular weight of copolymers was determined by theMark-Houwink relationship. The measured molecular weight of samples shows that we have reached a high molecular weight. Effect of different shear rate on solution viscosity was evaluated. The copolymer solutions showed a non-Newtonian shear thinning behavior. The performance of copolymers with respect to shear resistance and molecular weight were evaluated from point of view enhanced oil recovery application.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
