Reaction Conditions

Reaction Steps

Six percent crosslinked poly(allylamine) was made as stated in Example 82. To a flask were added the crosslinked poly(allylamine) (12.5 grams; 6% crosslinked; ground to ~30 mesh), (3-bromopropyl)dodecyldimethylammonium bromide (17.5 grams; made by reaction of 1,3-dibromopropane and N,N-dimethyl-1-aminododecane in diethyl ether), and methanol (334 mL). The mixture was heated to 65° C. with stirring. Upon reaching 65° C., aqueous sodium hydroxide (1.14 grams of 50% solution) was added and the stirring continued at 65° C. for 2 hours. Two additional aliquots of aqueous sodium hydroxide (1.14 grams of 50% solution) were sequentially added and the stirring continued at 65° C. for an additional 2 hours for each aliquot. Aqueous sodium hydroxide (1.14 grams of 50% solution) was then added and the stirring continued at 65° C. for an additional 12 hours. The mixture was then allowed to cool to room temperature.
