Abstract The inverse emulsions were prepared with arcylate as aqueous phase, coal oil as oil phase,a mixture of three kinds of surfactants（ Span80MA, Span80 and Twen80） as the emulsifiers.HLB value of Span80MA was worked out.The effects of concentration of emulsifier，aqueous phase volume fraction and monomer content on type and stability of emulsion were investigated.The results showed that HLB value of Span80MA was 4.0.The other optimal conditions forming steady water-in-oil emulsion were Span80MA∶Span80∶Twen80=0.7∶0.5∶0.2，emulsifier concentration was 7%,φwas 50% and monomer content was 2.0～3.0 mol/L .
