Abstract: Isocyanurate-contg. compsn. (I), liq. at room temp., with NCO content 23-31%, obtd. by trimerising mixt. of 80-30 wt.%, on total wt. of 4,4'-diphenylmethanedi-isocyanate and 20-70 wt.%, on total wt., of 2,4'-diphenyl methanedi-isocyanate in presence of trimerisation catalyst (II). (I) is prepd. by trimerisation at 0-160 deg.C, followed opt. by cooling and opt. by deactivation of (II).

Abstract: Elastic moulded polyurethane articles are prepared by reacting in solution in an inert polar solvent a linear isocyanate modified polyhydroxyl compound of M.W. 750-6000 and a melting point below 50 DEG C. having terminal -NCO groups with a dihydrazino-di-s-triazino compound in which monohydrazino-s-triazines are linked via a bivalent diamine radical, and moulding the resulting solution while removing the solvent by heating. The dihydrazino compound may have the formula where A is a diamine radical attached to the triazine rings via its nitrogen atoms and B is hydrogen chlorine or a monovalent aliphatic or aromatic group of 1-8 C or -OR, or -NR1R2, where R1 and R2 are hydrogen or monovalent aliphatic or aromatic groups of 1-8 C.
