Procedure

To a mixture of 236 g of HMDI with 25.0 g of cyclohexyl isocyanate (referred to hereinafter as CHI) was added 2.60 g of the carbodiimidization catalyst, and they were subjected to a reaction at 185° C. for 19 hours while nitrogen was bubbled thereinto, to obtain a carbodiimide resulting from HMDI and CHI (degree of polymerization=10).
