METHOD OF PRODUCING MODIFIED ORGANIC POLYISOCYANATE
-
, (2008/06/13)
A modified organic polyisocyanate having isocyanurate rings is produced by adding a trimerization catalyst, an organic phosphite, a surfactant and, if desired, a ferrocene compound to an organic polyisocyanate and/or partially urethanated organic polyisocyanate, converting at most 20 % by weight of all of the isocyanate groups into isocyanurate groups, and adding, if necessary, a terminating agent to the reaction system.
