Reaction Steps

A 500-ml, three-necked, round-bottomed flask was equipped with a stirrer, addition funnel, dry ice/acetone condenser, thermometer and electric heating mantle. The flask was flushed continuously with argon. The flask was charged with 167.2 g (0.55 equivalent) of dimethyl hexadecyl ammonium chloride (Sartomer Chemical Company, West Chester, Pa.), 0.028 g (0.27 milliequivalent) of triethylamine (Aldrich), and 250 g of isopropanol. To the stirred flask contents 65.2 g of the epoxy trisiloxane of Example 1 was added over a ten-minute period. The reaction mixture was stirred and heated at 80° C. for five hours to form a clear solution. The reaction mixture was cooled to ambient temperature and flushed overnight with dry argon. The solvent and other low-boiling materials were removed by rotary evaporation at 45° C. The yield of the quaternary ammonium salt (Compound II), a light yellow oil, was 118 g (87%). The elemental analysis was as follows:
