반응 단계

Xylene (15 g), behenyl methacrylate (15 g), lauryl acrylate (2 g), are charged to a reactor equipped with a stirrer, a heater, a thermometer, and a nitrogen-bubbling duct. The reactor is flushed with nitrogen gas and sealed. Then vinyl acetate (2 g) is charged. The reactor is heated to 60° C. and 2,2′-azobis(2-methyl, ethyl-propionitrile) (0.06 g) is added. The reaction mixture is heated in the closed system at 75° C. for one hour, at 90° C. for 30 minutes, and at 110° C. for one hour to provide behenyl methacrylate/lauryl acrylate/vinyl acetate polymer having a number average molecular weight of 41,008 Daltons with polydispersity 3.4. The viscosity of the polymer is 135 cP at 20° C. as a 40% solution in toluene.
