the p aminophenol is present as a chain stopper and in a minor amount such that its effect on the morphology of the final poly siloxaneimide is negligible the reaction mixture was heated to reflux in 1 2 hours and 1292 grams of monochlorobenzene were removed by distillation the reaction mixture was refluxed for 10 hours after cooling the solution was filtered and 1860 grams of n methylpyrrolidone were added and mixed in the solution was mixed with methanol using 3 5 liters of methanol for every 500 milliliter of solution causing precipitation of poly siloxane imide after precipitation the methanol was decanted from the precipitate which was washed twice with 8 liters of methanol the precipitate was air dried overnight and then dried in a circulating air oven at 50 u00b0 60 u00b0 c until the polymer solids content was gt 98 5 the yield was approximately 500 grams the weight average molecular weight is about 100 000 the poly siloxaneimide prepared in example 1 was dissolved in diglyme 90 u00b0 c for 10 hours at a 40 solids concentration and filtered to 116 5 grams of the resultant solution were added 115 5 grams of silver flake gp 0006 chemet corporation and 17 25 gram of 50 s silver flake metz metallurgical corporation and 0 65 gram of dow corning 1400 antifoam these materials were blended in a planetary mixer for one.
