Resumen en inglés The molecular weight of poly[acrylamide-co-vinylpyrrolidone-co-(vinyl benzyl) trimethyl ammonium] chloride is determined from numerical and experimental data of the reduced viscosity of polymer in brine (with 0.1M NaCl) at normal temperature and pressure. The methodology is based on the numerical results of the mean radius of gyration of polymer and reduced viscosity which is derived from the molecular dynamics simulation of the mixture by using the NPT ensemble. The formula of the reduced viscosity as a function of the polymer radius of gyration and the polymer concentration in brine is proposed
