Monomeric surfactant was synthesized fronts styrene derivative, and vesicle solution was prepared by sonication. This vesicle solution was photopolymerized by uv irradiation and crosslinking percent was controled by amount of divinylbenzene. Using 14
C sucrose as a substrate, permeability was examined. The results showed that retention portent was increased by polymerization and crosslinking also had an effect on retention percent. When dialysis medium was changed from water to 23% ethanol, above effects were showed more clear.
