Vorschrift

Isopar (10 g), behenyl acrylate (15 g), and lauryl methacrylate (2 g) are charged to a reactor equipped with a stirrer, a heater, a thermometer, an additional funnel containing a solution of maleic anhydride (2 g) in toluene (5 g), and a nitrogen-bubbling duct. The reactor is flushed with nitrogen gas and sealed. The reactor is heated to 85° C. and tert-butyl peroxibenzoate (0.2 g) is added. The reaction mixture is heated in the closed system at 85° C. for three hours, and tert-butyl peroxibenzoate (0.2 g) is charged two more times. Then the reaction is heated at 100° C. for one hour, at 110° C. for 30 minutes and at 125° C. for one hour to provide behenyl acrylate/lauryl methacrylate/maleic anhydride polymer having a number average molecular weight of 20,659 Daltons with polydispersity 1.8. The viscosity of the polymer is 110 cP at 20° C. as a 40% solution in toluene.
