Abstract: The prodn. of isocyanurate gp.-contg. polyisocyanates (A) comprises partial trimerisation of (cyclo)aliphatic di-isocyanates (B) in the presence of tetra-alkylammonium alkyl carbonates of formula (I) and/or quat. ammonio-alkyl carbonate betaines of formula (II) as catalyst(s), followed by deactivation of the catalyst on reaching the required deg. of trimerisation. In formulae, R , R , R = 1-20 C alkyl, 5-6C cycloalkyl, 7-10C aralkyl or Ph; or R + R can form a 5- or 6-membered cycloalkyl gp., or R + R + N can form a 5- or 6-membered ring with another N or O as bridging gp. or R + R + R + N can form a multi-membered ring with one or more extra N and/or O bridges; R = 1-4C alkyl; R = 2-20 C alkylene, 5-6C cycloalkylene, 7-10C aralkylene or phenylene; or R + R = alkylene gp. which forms a 5- to 7-membered ring with a N bridge. Pref. trimerisation catalysts are carbonates of formula (III), (IV), or (V), or betaine carbonates of formula (V), (VII) or (VIII). Trimerisation is carried out at 30-150 degrees C and the catalyst is deactivated with dibutyl phosphate (DBP); unreacted monomeric di-isocyanate is then removed. Pref. di-isocyanates are (cyclo)aliphatic di-isocyanates obtd. by a phosgene-free process, esp. by thermal cleavage of (cyclo)aliphatic dicarbamate esters; esp. pref. di-isocyanates obtd. by this method are 1,6-hexamethylenedi-isocyanate (HDI), 2-butyl-2-ethyl-pentamethylene-1,5-di-isocyanate and 1-isocyanato-3-isocyanatomethyl-3,5,5-trimethylcyclohexane (IPDI).
