Reaction Steps

To a 500-mL round bottom flask was added 1,10-bis(diallylmethylammonio) decane dibromide (21.1 g), diallylmethyldodecylammonium bromide (21.1 g), and water (52 g). Azobisisobutyramidine dihydrochloride (1 mL of a 50% aqueous solution) was added and nitrogen was bubbled through the mixture for 1 hr. The mixture was then heated to 60° C. with stirring for 18 hr. The resulting gel was allowed to cool to room temperature. The gel was removed and ground in a blender with water (250 mL). The solid was collected by filtration and resuspended in methanol (250 mL). The solid was collected by filtration and resuspended in methanol (250 mL). After stirring for 1 hr, the solid was collected by filtration and resuspended in aqueous NaCl (250 mL of 1.5 M solution). After again stirring for 1 hr, the solid was collected by filtration. The aqueous NaCl rinse was repeated twice more, and the solid was rinsed with water until the conductivity of the rinse reached 0.08 mS/cm. The solid was dried in a forced-air oven at 60° C. to yield 17.6 g of product.
