| Abstract：The synthesis of soap-free emulsion by two steps was studied, and the properties of emulsion were tested. The factors affected the polymerization rate and the properties of soap free emulsion were studied including initiator dosage, monomer ratio, polymerization temperature and time. The optimum synthesis condition was as followings: MA/BA(mass radio) was of 70/30; the amount of initiator was of 0.5% (mass percentage content of monomers); the amount of emulsifier was of 3% (mass percentage content of monomers); the reaction temperature was of 70℃; the reaction time was of 3.5 hours. This soap-free emulsion was with high solid content, good stability, strong adhesion and water resistance. |
