| Popis: |
A study was made on plasma-initiated polymerization of polyacrylamide (PAM) with high superabsorbent property. The viscosity-averaged molecular weight Mη of this PAM was 6.2×106g/mol in the measurement of viscosity by using water as solvent. Its conversion and water absorption calculated are 70% and 300g/g respectively. The effects of plasma discharge time, polymerization temperature and duration on the conversion and the molecular weight of the products were also investigated. The results of this study suggested that the method of plasma initiated polymerization could greatly enhance the molecular weight and water absorption property of the polymer. |
