Vorschrift

Xylene (15 g), behenyl acrylate (15 g) and lauryl methacrylate (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 80° C. for two hours to provide behenyl acrylate/lauryl methacrylate/vinyl acetate polymer having a number average molecular weight of 47,750 Daltons with polydispersity 4.5. The viscosity of the polymer is 168 cP at 20° C. as a 40% solution in toluene.
