The reverse microemulsion of Span80-Tween80/isooctane/AM-H2O was prepared and polymerized

and the regular changes of electrical conductance at different HLB values were studied with the conductivity method.The effects of adding n-butanol

NaCl and NaAc on the changes of conductivity properties were discussed.The micro-structure and the size distribution of PAM particle were invested with TEM

AFM

DSC

laser nanometer measurement before and after polymerization.The results showed that the change of electrical conductance was lower when HLB value approached 5.4

it almost had no change when the concentration of n-butanol was 25 g8226;L-1

and its stability was enhanced when 50 g8226;L-1 NaCl or 25 g8226;L-1 NaAc was added in the system.Polymer microemulsion relative molecule weight（MR）5.64×106 and solid content of PAM 32% was obtained after polymerization

and the polymer was mono-disperse

globular nanometer material.The diameter of PAM particle(D) was 140 nm

and its size distribution was narrow.The surface area and glass transformation temperature (Tg) of the polymer was 21.684 m28226;g-1 and 193℃

respectively.
