| Abstract: | Using new type compound initiating system to polymerize acrylamide monomer with homopolymerization posthydrolysis process, super-high molecular weight polyacrylamide for oil-displacing agent used in oil field is synthesized. The molecular weight of which is up to 25 000 000, hydrolytic degree is adjustable between 20 % and 30 %, filtration ratio<1.3. Factors, such as hydrolytic reagent, hydrolytic temperature, hydrolytic time and latent solvent that affect molecular weight of polyacrylamide are also studied and optimum process parameters of hydrolysis are obtained. |
