실험 절차

The ion pair of the distearyl dimethyl ammoniun cation and the octadecene-maleate copolymer anion was prepared as follows. 4 g (0.05 mole) of 50% NaOH was added to 100 ml of water and 29.3 g (0.05 moles) of distearyl dimethyl ammonium chloride was dispersed in the mixture. It was heated to 85° C. and 8.8 g (0.05 moles of carboxylate) of 1:1 copolymer of octadecene and maleic anhydride was added as a powder. The mixture was stirred at 85° to 90° C. for 10 hours, during which the octadecene-maleic anhydride copolymer particles disappeared. The water phase gradually cleared and gelled particles of the ion pair formed. The product was separated by decanting the water. The product weighed 57.5 g and contained 36.1% water. The remaining water was removed by spreading the gelled product in a thin layer and passing air at room temperature across it. It was ground in a Waring Blender to a fine non-tacky powder.
