Abstract: A series of poly phenyl glycidyl ethers with different molecular mass (PPGE) was synthesized via the polymeration of phenyl glycidyl ether in the presence of n-BuLi.Sodium poly phenyl glycidyl ether sulfonate was synthesized via the sulfonation of the poly phenyl glycidyl ether with sulfuric acid.We studied the relationship between the performance of the Polymer surfactant and its structure.The result shows that the range of molecular mass of PPGE is from 1 000 to 3 000 and its sulfonation degree is from 150% to 250%,as well as the increase of the dynamic surface activity with the SPPGE concentration increase from 2.5 g/L to 20.0 g/L,while the time of the DST achieving interface equilibrium is shorted,and the DST curve becomes lower.Within the scope of the SPPGE concentration under the study,in the beginning period,the adsorption is under diffusion control regime,while in the later period,it belongs to mixed kinetic adsorption,and the higher the SPPGE concentration,the bigger the adsorption barrier ε_a and the smaller the effective diffusion coefficient Deff.The SPPGE has a high critic micelle concentration and its CMC is about 11.0 g/L,and is less affected by the change of sulfonation degree.The change of the molecular mass can affect the surface activity effectively,among three different SPPGE samples,the one the molecular mass of 1 595 has the lowest DST curve with CMC being 10.9 g/L and γ_min being 48.93 mN/m.
