of acetoxy groups to hydroxy groups a four neck 5 l glass round bottom flask fitted with a chilled water reflux condenser a themowell with thermocouple a nitrogen inlet and outlet an overhead stirrer and an external heating mantle was charged with a reaction mixture of 333 5 grams 2 06 moles of asm and 680 3 grams 3 27 moles of isobornyl acrylate with stirring to this mixture was then added 1087 6 grams of methanol and 120 8 grams of tetrahydrofuran the entire reaction mixture was heated to 66 u00b0 c over a period of one hour and at this time the polymerization was initiated by adding 33 8 grams 75 concentration 2 9 mole percent based upon total number of moles of monomers of t bpp diluted in 35 0 grams of methanol after one hour of polymerization 6 65 grams of t bpp diluted in 6 65 grams of methanol was added at each hour for the next 3 hours 6 65 grams of t bpp in 6 65 grams of methanol was added after each addition a sample of the polymer mixture was withdrawn from the reactor and analyzed for the unreacted monomers by capillary gas chromatography gc the polymerization reaction was continued for about a total period of 18 hours at the end of this period analysis of the final polymer mixture by capillary gc showed greater than 98 by weight conversion of the monomers to.
