| 摘要 | NEW MATERIAL:1,6,11-Undecane triisocyanate of formula I. USE: A raw material for polyurethane and polyurea usable for coating materials, films and adhesives, capable of imparting improved properties, e.g. light stability, weatherability, and solvent resistance, and good quick drying property and excellent surface hardness to films. PROCESS: 1,6,11-Undecanetriamine hydrochloride of formula II is suspended in an insert solvent, e.g. a chlorinated hydrocarbon, and reacted with phosgene at 100W170°C to give the compound of formula I. The starting compound of formula II is obtained by heating ε-caprolactam, ε-amino caproic acid, or their polymer in the presence of a strong base, e.g. an alkali metal oxide, at 300°C or above, and by reducing the resulting compound of formula III with hydrogen in aqueous ammonia.
