Abstract: PROCESS FOR THE PREPARATION OF POLYESTER POLYOLS A process for the preparation of polyester polyols having an acid number of less than l, a hydroxyl number of approximately 20 to about 400, and having a functionality of efficaciously 2 to 3, wherein polycarboxylic acids and/or their anhydrides and multivalent alcohols are polycondensed, preferably in the absence of common esterification catalysts, at temperatures of from about 150.degree. to 250.degree.C, optionally under reduced pressure, up to an acid number of from 20 to 5. The resulting polycondensate is then oxyalkylated per carboxyl group using from 1 to 5 moles of an alkylene oxide, for example 1,2-propylene oxide and/or preferably ethylene oxide, in the presence of at least one tertiary amine catalyst from the group consisting of N-methylimidazole, diazabicyclo¢2,2,2!octane, diazabicyclo¢5,4,,0!undec-7-ene and pentamethyldiethylenetriamine and mixtures thereof, in a quantity of from about 0.001 to 1.0 weight percent based on the weight of the polycondensate, at temperatures from about 100 to 170.degree.C and under a pressure of about 1 to 10 bar.

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.

Abstract: PROCESS FOR THE PREPARATION OF FLEXIBLE POLYURETHANE FOAMS INVOLVING THE USE OF ALIPHATIC MONOAMINES The invention relates a process for the preparation of a polyurethane foam by reacting an organic polyisocyanate, polyol, and primary or secondary aliphatic monoamine in the presence of a blowing agent and catalyst. The amines are used in quantities of 0.1 part to 10 parts by weight per 100 parts per weight of polyol. The highly elastic polyurethane flexible foams are suited for the manufacture of upholstered furniture, matresses, automobile seats and head supports, as well as particularly for molded foams. The semi-rigid polyurethane foams are used as foam backing of dashboards in automobiles, thermal and sound insulation in buildings and vehicles, and for impact absorption in packaging materials.

Abstract: Stable melamine-polyoxyalkylene polyether polyol dispersions are prepared by the in situ reduction of melamine particles wherein 90 percent of the melamine particles have a particle size of less than 10 microns. Stabilizers for the melanine-polyol dispersion are selected from the group eonsisting of a) silicic acids and silicates, b) salts of perfluorinated alkyl carboxylic acids having 4 to 20 carbon atoms, salts of alkyl sulfonic acids and perfluorinated alkylsulfouic acids having 4 to 20 carbon atoms and polyperfluoroether polyols having molecular wights of 300 to 6000, and c) salts of fatty alcohol sulfates having 6 to 30 carbon atoms. These dispersions are useful for the preparation of polyurethane foams.

Abstract: Pigment dyeing fibres of cotton, viscose, wool, silk, cellulose acetate, polyamide, polyester, polyacrylonitrile, asbestos and glass is effected by applying a liquor containing a pigment, a binder, polyvinylcaprolactam or a copolymer thereof both of which polymers being soluble in the dye liquor and, optionally, dyeing auxiliaries and drying the material thus treated. Specified comonomers are vinylimidazole, vinyl pyrrolidone, methacrylamide, acrylic acid, ethyl acrylate and vinyl acetate. The binder may be any known cross-linkable copolymers, e.g. as aqueous dispersions, or curable precondensates (many listed). Specified auxiliaries are plasticisers, emulsifiers, thickeners, protective colloids, fillers as well as acid or alkaline catalysts. The dye liquors may be applied by padding, the fibres may then be dried at 50-100 DEG C. and cured at 100-200 DEG C. Examples are given.
