Procedure

Next, [C4F9SO2N(CH3)CH2]2CHOC(O)NH(CH2)3Si(OCH2CH3)3 was prepared as follows. A three-necked round bottom 500 ml flask fitted with a stirrer, heating mantle, condenser, nitrogen inlet, Dean-Stark trap and thermometer was charged with about 204.6 grams of the [C4F9SO2N(CH3)CH2]2CHOH (0.3 mol), and about 250 grams methyl ethyl ketone. The mixture was heated for about 1 hour at about 100° C. and about 50 grams of material was removed using the Dean-Stark trap. The mixture was cooled to about 30° C., and about 74.4 grams of OCN(CH2)3Si(OCH2CH3)3 (0.3 mol), and three drops of stannous octanoate were added. The resulting mixture was heated at about 75° C. under nitrogen for about 16 hours.
