Abstract: LIQUID ISOCYANURATE GROUP-CONTAINING POLYISOCYANATE MIXTURES OF 4,4'- AND 2,4'-DIPHENYLMETHANE DIISOCYANATE, METHOD FOR THEIR PREPARATION AND THEIR USE IN POLYURETHANE OR POLYISOCYANURATE PLASTICS Isocyanurate group-containing polyisocyanate mixtures which are liquid at room temperature and which have an isocyanate group content of from 23 to 31 weight percent are obtained through the partial trimerization of a mixture comprised of from about 80 to about 30 percent by weight 4,4'-diphenylmethane diisocyanate and from about 20 to about 70 percent by weight 2,4'-diphenylmethane diisocyanate in the presence of a trimerization catalyst, preferably an adduct of tri(dimethylaminopropyl)-s-hexahydrotriazine, 1,2propylene oxide, and 2-ethylhexanoic acid, and, in some cases, after chemical deactivation of the catalyst.

Abstract: DIPHENYLMETHANE DIISOCYANATE-BASED LIQUID POLYISOCYANATE MIXTURES CONTAINING URETHANE GROUPS, PROCESS FOR THEIR PREPARATION AND THEIR USE FOR THE PREPRATION OF FLEXIBLE POLYURETHANE FOAMS Diphenylmethane diisocyanate-based liquid polyisocyanate mixtures containing urethane groups and having an isocyanate content of from 12 to 30 percent by weight are obtained by reaction of a polyoxypropylene polyoxyethylene polyol containing 5 to 30 percent by weight of oxyethylene with diphenylmethane diisocyanate-based isocyanates. These polyisocyanate mixtures are storage stable at low temperature and yield flexible polyurethane foams having improved mechanical properties.
