Vorschrift

We combined 0.0830 g TPAO, 60.41 g of m-TMI, and 25.04 g cyclohexylisocyanate. After heating at 150° C. for 7 hours, IR showed nearly complete conversion of isocyanates to carbodiimides. 1H--NMR indicated the desired product contaminated with 1,3-dicyclohexylcarbodiimide, and 1,3-bis[2-(3-isopropenylphenyl)-2propyl]carbodiimide.
