| Abstract: | Objective To synthesize the polyacrylamide with ultrahigh molecular weight. Methods The monomer was purified by recrystallization,absorption in active carbon and cationic exchange resin.The polymerization of aqueous solution of acrylamide (AM) was carried out by redox system initiator-KPS-BPC. Results The intrinsic viscosity of acquired polyacrylamide (PAM) is 17.8 dL/g (30, 1 molL-1NaNO3) and its decomposition temperature is 410. Conclusion Molecular weight of PAM relates to monomer's purity and concentration, appropriate initiator and control of temperature. |
