| Abstract: | Aim\ To synthesize polyacrylamide(PAM) by precipitation polymerization. Methods\ Polyacrylamide was synthesized to adopt static polymerization condition and the pattern of feeding initiator in batch, acetone as solvent, BPO N, N dimethylaniline as redox initiator. The influence of each factor on the relative molecular weight and properties of PAM is discussed. Results\ The powdery PAM having good water solubility was obtained, its relative molecular weight was over 900,000. Conclusion \ The powdery PAM having good water solubility is synthesized directly by precipitation polymerization. The concentration of initiator and temperature of polymerization were important factors on the relative molecular weight of PAM. |
