| Abstract: | Main factors (such as hydrolytic reagent, temperature, time and concentration) affecting molecular weight of polyacrylamide have been analysed using orthogonal design. Post-hydrolysis is carried out at the concentration of 8% ,temperature of 90 C in the presence of NaOH as hydrolytic reagent. Polyacrylamide with molecular weight up to 25 million ,hydrolytic degree of 25. 8% and filtration ratio < 1. 29, which can be used as oil displacing agent has been synthesized by combination of hydrolysis technology with polymerization technology. |

| Keywords: | polyacrylamide post-hydrolysis hydrolysis parameters super high molecular weight |
