CATALYST FOR THE REACTION BETWEEN A COMPOUND THAT CAN REACT WITH ISOCYANATE GROUPS AND AN ALIPHATIC DIISOCYANATE WITH ONE ISOCYANATE GROUP BOUND TO A PRIMARY CARBON ATOM AND ONE ISOCYANATE GROUP BOUND TO A TERTIARY CARBON ATOM

摘要

Primary carbon atom can be tied to isocyanate groups and aliphatic diisocyanate and an isocyanate group in a kind of compound the present invention relates to the reaction of catalyst and an isocyanate group is tied on tertiary carbon atom. The catalyst is that a kind of ion source metal complex is based on periodic system of the metallic element from group an III, IV or VII, has at least one tradable counter ion. It is preferred that metal is titanium, zirconium, manganese or tin.
