摘　　要：对复配乳化剂(span+tw een)、丙烯酰胺(AM)、(2-甲基丙烯酰氧乙基)三甲基氯化铵(M ADQUAT)、2-丙烯酰胺基-2-甲基丙磺酸钠(N aAM PS)和环己烷组成的微乳液体系进行了研究,研究了单体总质量浓度、AM摩尔含量和阴阳离子单体配比改变对形成微乳液需要的适宜H LB值和最小乳化剂用量(Sm in)的影响。通过测定体系的电导率,研究了温度、乳化剂质量含量和H LB值的改变对微乳液相转变的影响,用目视滴定法绘制了微乳液体系的拟三元相图,并用电导法对微乳液透明区进行了类型划分。The formation of microemulsion system containing emulsifier, acrylamide（AM）, 2- （methacryloyloxy）ethyhrimethyl ammonium chloride （MADQUAT） , sodium-2-acrylamido-2- methyl-propane-sulfonate （NaAMPS） and hexamethylene was studied. The optimum HLB values and the minimum weight percentage content of emulsifiers were obtained when the monomers concentration, the mole content of AM, the mole ratio of MADQUAT and NaAMPS were different. The optimum formulation can be described as： monomer concentration （50 %） ,the mole ratio n（AM）/n（MADQUAT）/n（NaAMPS）=8 ： 1 ： 1, HLB=10. 82. And the effects of the temperature, the emulsifier content, the HLB value of emulsifier on penetration and phase inversion of the system have been investigated by determining the conduct of microemulsion. At the end, the pseudo-ternary phase diagram of microemulsion was drawn and be divided into W/O, bicontinuous（BC） and O/W districts basis of the conduct of system.
