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: Crystallite suspensions containing from 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester prepared through condensation polymerization, and having a molecular weight factor per double bond of 154.4 to 408, as the dispersed phase, and from 30 to 97 weight percent of a polyhydroxyl compound having a functionality of from 2 to about 8, a hydroxyl number of from 20 to 800, and a melting point of less than 30 DEG C. as the coherent phase are suitable for preparing non-cellular and cellular polyurethane- or polyurethane group-containing polyisocyanurate foams.

Abstract: Stable dispersions which contain a) as a disperse phase, expediently from 5 to 35 % by weight of a polyester made from isophthalic acid, terephthalic acid or a mixture of terephthalic acid and aromatic and/or aliphatic dicarboxylic acids and alcohols having 1 to 6 carbon atoms, having a melt viscosity at 150 DEG C of from 15 to 3000 mPa.s, and b) as the coherent phase, expediently from 65 to 95 % by weight of an alcoholysate mixture having a mean functionality of from 2 to 4, a hydroxyl number of from 250 to 700 and an acid number of from 0 to 5, prepared by alcoholysis of a polyalkylene terephthalate having a relative viscosity of greater than 1.1 by means of at least one polyhydric alcohol. The dispersions are particularly suitable for the preparation of polyurethane foams or polyisocyanurate foams containing polyurethane groups, the foams having improved flame resistance and low evolution of smoke.

Abstract: 1. An adduct obtained by a functionality of 2 to 6, a hydroxyl number of 20 procedure analogous to the Michael reaction, by reacting a) an olefinically unsaturated polyester polyol having to 800, an acid number of 0 to 15 and a molecular weight of 150 to 3000 per double blond, with b) 0.1 to 1 mole, per mole of olefinically unsaturated double bond of component (a), of an alkylene polyamine of the formula H2 N-R-NH-R'-X, where X is an NH2 or OH group, and R and R' are identical or different, linear or branched alkylene radicals of 2 to 12 carbon atoms.
