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 BOUNDTO A TERTIARY CARBON ATOM

摘要

THE INVENTION RELATES TO A 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. THE CATALYST IS AN IONOGENIC METAL COMPLEX BASED ON A METALLIC ELEMENT FROM ONE OF THE GROUPS III, IV OR VII OF THE PERIODIC SYSTEM, WITH AT LEAST ONE EXCHANGEABLE COUNTERION.PREFERABLY THE METALLIC ELEMENT IS TITANIUM, ZIRCONIUM, MANGANESE OR TIN.
