Reaction Steps

To a flask similar to that used in Example 12, there were added 10.0 g (0.056 mole) of a mixture of (3-isocyanatocyclohexyl) methylisocyanate and (4-isocyanatocyclohexyl)methylisocyanate (obtained by phosgenation of a mixture of (3-aminocyclohexyl) methylamine and (4-aminocyclohexyl)methylamine; hereunder referred to as "ICMI") and 3.3 g of butyl acetate to dissolve the former in the latter and the temperature was adjusted to 25° C. with stirring in a nitrogen gas blanket. 0.4 g (3.2×10-4 mole) of a catalyst B (prepared in the same manner as in Example 12) was added thereto, then the flask was externally warmed or cooled to control the temperature of the solution to 60° C.
