Catalysts for the reaction of an aliphatic diisocyanate having an isocyanate group one that is attached to a tertiary carbon atom and isocyanate group one attached to primary carbon atoms and compounds capable of reacting with isocyanate groups

摘要

(57) [Abstract] The present invention, an aliphatic diisocyanate having an isocyanate group one that is attached to a tertiary carbon atom and the isocyanate group of the one attached to primary carbon atoms and compounds capable of reacting with isocyanate groups relates to a catalyst for the reaction with. The catalyst is an inorganic metal complex with exchangeable counterions at least one based on metal element selected first III of the periodic table, from one of the group VII or IV. Preferably, metal is tin, titanium, or zirconium.
