| Abstract: | Monodisperse polyacrylamide(PAM)sphere was prepared in ethyl acetate/ethanol media using PVP as the stabilizer and AIBN as the initiator by dispersion polymerization. The influence of the polymeric molecular and conversion by reaction time, the solvent composition, the concentrations of the stabilizer and monomer and initiator were studied. |
| Keywords: | dispersion polymerization polyacrylamide conversion molecular |
