A cycloaliphatic polyisocyanate compound, a process for the preparation thereof, a polyurethane therefrom, and an adhesive composition |
摘要 |
<p>The invention relates to a cycloaliphatic polyisocyanate represented by general formula (1) described below, <CHEM> in which Y1 is a divalent saturated aliphatic hydrocarbon residual group, for example, 3-isocyanatemethyl-5,5-dimethylcyclohexylisocyanate. The invention also relates to a process for manufacturing the above polyisocyanate by a reaction for conversion into an isocyanate of 3-aminomethylcycloalkyl amines which is obtained by a reductive amination of 3-formylcycloalkanones or 3-formylcycloalkenones obtained by oxidation of 3-methyl group in 3-methylcycloalkanones or 3-methylcycloalkenones. Further, 3-isocyanatemethyl-5,5-dimethylcyclohexylisocyanate having the chlorine content of not more than 10 ppm is optionally obtained using dimethylcarbonate by a phosgene method or a nonphosgene method.</p> |
