NEW ISOCYANATE COMPOUND, REACTIVE LIQUID MEDIUM AND FILM MATERIAL USING THE ISOCYANATE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an isocyanate compound which gives a dense film material having high gas barrier ability and heat resistance, a reactive liquid medium in which the isocyanate compound is dissolved and dispersed and a film material obtained from it. SOLUTION: The compound has a molecular skeleton comprising dendorimers and highly branched polymers and isocyanate groups having 4 or more functions on the surface. The compound has isocyanate groups on the surface of organic particles with a particle diameter of 1-50 nm and is a favorable raw material for polyureas and polyurethanes. The reactive liquid medium has a low viscosity and is suitable for coatings and the like. COPYRIGHT: (C)2005,JPO&NCIPI
