摘要：

Vinyl acetate (VAc) was polymerized with ammonium persulfate in microemulsions prepared from VAc, sodium dodecyl sulfate, n-propanol and water. The polymerization rates were smaller than those in emulsion. The reaction orders versus the initiator and tenside concentration were 0.9 and -0.5, respectively. The polymerization rate and molecular weights decreased by increasing the surfactant and the cosurfactant concentrations. By cooling the finally obtained microemulsions, a polymer solution coacervation took place.
