実験手順
To 288 g of HMDI was added 20 g of cyclohexylamine and they were stirred at 100° C. for one hour while nitrogen was bubbled thereinto and subsequently 2.9 g of the carbodiimidization catalyst was added thereto, after which the resulting mixture was subjected to a reaction at 185° C. for 30 hours, to obtain a carbodiimide resulting from HMDI and having terminal urea bonds (degree of polymerization=10).
