摘　　要：Lipophilic epoxy resin E-44 is introduced into hydrophilic PEG-6000 molecule through nucleophilic addition reaction between the epoxy group and the hydroxyl group under catalysis of boron tri- fluoride etherate [C2 H5]2O·BF3]to syn the size aspeciale mulsifier EP 1 for epoxyres in .EP 1ha a fair solubility in water and acertainsur faceactivity .Its surfacetensio non water is 44m N/matcritical micelle concentration (CMC) .A high mechanical stablee mulsion with averageparticle size of 1 0 7 3nm has been prepare dusingEP 1 as anemulsi fier by phasein versione mulsionprocess and there from a nanometer emulsion with average particle size of 91 . 8 nm has been obtained .Lipophilic epoxy resin E-44 is introduced into hydrophilic PEG-6000 molecule through nucleophilic addition reaction between the epoxy group and the hydroxyl group under catalysis of boron tri- fluoride etherate [C2 H5]2O·BF3]to syn the size aspeciale mulsifier EP 1 for epoxyres in .EP 1ha a fair solubility in water and acertainsur faceactivity .Its surfacetensio non water is 44m N/matcritical micelle concentration (CMC) .A high mechanical stablee mulsion with averageparticle size of 1 0 7 3nm has been prepare dusingEP 1 as anemulsi fier by phasein versione mulsionprocess and there from a nanometer emulsion with average particle size of 91 . 8 nm has been obtained .
