Conditions

Temperature: 60 °C

Procedure

Toluene (15 g), stearyl acrylate (15 g), hexyl methacrylate (3 g), and styrene (3 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. 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 85° C. for three-four hours, to provide stearyl acrylate/hexyl methacrylate/styrene polymer having a number average molecular weight 34,600 Daltons with polydispersity 2.1. The viscosity of the polymer is 40 cP at 20° C. as a 40% solution in toluene.
