| Abstract: | An anion stabilizing agent of dispersion polymerization was formed in the paper.The intrinsic viscosity was 2～4 dL/g and concentration was 20 % and viscosity was 200～300 mPa·s.The characteristics of the stabilizing agent is of macromolecule and surfactant.It had outstanding disperse stability.Disperse emulsion of acrylic acid had been synthesized by using the stabilizing agentbv.The total surface area of the dispersion particles was 0.28 m 2 /g;the average particle diameter of surface area was 19.33 μm;the volume average particle diameter was 228.82 μm.Its stability was longer than half a year. |
