The pseudo-ternary phase diagram of the emulsifier mixture of Span20 and Tween80

acrylamide(AM)

2-(methaeryloyloxy)-ethyhfimethyl-ammoniumchloride (MADQUAT)

sodium-2-aerylamido-2-methyl-propane-sulf-onate (NaAMPS) and eyclohexane was drew by a lot of experiments The kinetics for the inverse microemulsion polymerization of acrylamide

cationic monomer and anionic monomer were carried out by using (NH4)2S2O8-NaHSO3 as redox initiator．The apparent activation energy of the polymerization was calculated by Arrhenius equation to be 68.10 kJ/mol

and the effects of monomer concentration

inifiator concentmtion and emulsifier concentration on polymerization rate and intrinsic viscosity of polymer were determined．The kinetics equations of Rp and [η] could be expressed as Rp ∝[M]1.74[APS]0.60[E]-1.28

and [η] ∝[M]0.78[APS]-0.23[E]-0.71 respectively．The mechanism of the inverse mieroemulsion polymerization was also discussed．
