Abstract:

Three polymerizable nonionic surfactants(Ⅱ-PEG400, Ⅱ-PEG1000, Ⅱ-PEG2000) were synthesized from 2,4-toluene dissocyanate(TDI), allyl alcohol and polyethylene glycol, and characterized by FT-IR. Results indicate that as the molecular mass of polyethylene glycol increases, the conductance is increased obviously, and the surface tension is decreased from 36.28 mN/m to 31.30 mN/m, while the cloud point is increased from 39.6  ℃ to 58.9 ℃. Their emulsifying abilities to BA, MMA and BMA are superior to that of OP-10, and the surfactants is homopolymerize or copolymerize with acrylate at 70 ℃ under the initiation of AIBN.

Key words: polymerizable nonionic surfactant, conductance；surface tension； emulsifying ability
