| Abstract: | Main factors ( such as hydrolytic reagent, temperature, time, concentration, gel grain, heating means and drying time, drying temperature) affecting molecular weight of polyacrylamide have been studied. Optimum process parameters of post-hydrolysis are obtained. Based on these parameters, hydrolysis and drying conditions of appropriating to industrialization producing ultrahigh molecular weight polyacrylamide were assured. |
