Reaction Steps

To a solution of 136 parts of imidazole (2.0 moles) in 408 parts of ethyl acetate, 278 parts of bisphenol A dicyanate (1.0 mole; manufactured by Interez, Louisville, Ky.) in 834 parts of ethyl acetate were added slowly. The reaction temperature was maintained at 60°-65° C. during addition. After the addition, the mixture was stirred for another half hour at 60°-65° C. The batch was cooled down to 30°-35° C. and the precipitates were filtered by suction filtration. The white powder was dried under vacuum at 50°-60° C. M.P.=175°-177° C.; actual yield=95-97%.
