Abstract

A catalyst system for the trimerisation of isocyanates contains (1) a quaternary ammonium hydroxide (I) (where R1, R2, R3, R4 are alkyl or hydroxyalkyl of 1 to 6C, cycloalkyl of 5 or 6C, benzyl, phenyl or may be pyridine), and (2) compound (III) from (a) methanol, (b) a C2-6 oxime and (c) a phenol where R is halogen, methyl or amino; n is 0, 1, 2 or 3; m is 0 or 1, and when m is 1 the 2 OH groups are in the meta or para position. The catalyst system is more effective than present systems. Smaller concentrations and shorter reaction times are required and trimerisation on an industrial scale is possible. The trimers are used in paints, coating compositions, adhesives, -rubbers.
