And the use of pre-emulsion seed microemulsion method, sodium dodecyl sulfate (SDS) and nonylphenol polyoxyethylene ether (OP-10) as emulsifier, the successful preparation of the styrene microemulsion. On this basis, the amount of emulsifier and the ratio of compound, polymerization temperature, the seed monomer, and the outer layer of monomer dropping rate of the average particle size of styrene microemulsion. Experimental results show that the polymerization temperature at 68℃~ 78℃ within the composite amount of emulsifier, the total mass of 3% to 5% SDS: OP-10 mass ratio of 4:1 to 6:1, seed monomer amount of the total mass of monomer 8% to 10%, the outer layer of monomer dropping rate of 4.8 to 9.6ml/min obtained average particle size in the nanometer range and better distribution of styrene microemulsion.
