Abstract: The inverse suspension polymerization of acrylamide has been carried out in the presence of emulsifier Span 20 and Span 80, and K2S2O8 as initiator. The polymerization rate Rp was found to be proportional to [M]0.13 and to [I]0.11, and the molecular weight of polymer Mw varied with [M]1.1 and [I]0.11 respectively. The overall activation energy for polymerization of aerylamide at 40~50℃ was calculeted to be 30.5 kJ/mol.

Key words: inverse suspension polymerization, acrylamide
