Reaction Steps

The same isocyanuration reaction as in Example 1 was carried out except that 3,290 g of hexamethylene diisocyanate and 210 g of "Takenate 500" (xylylene diisocyanate produced by Takeda Chemical Industry Co., Ltd.) were used instead of 3,500 g of hexamethylene diisocyanate, and the amount of the isocyanuration catalyst used in Example 1 was changed to 4.7 g. There was obtained 4,219 g of the reaction mixture containing the deactivated catalyst.
