Abstract: MANUFACTURE OF FLEXIBLE FOAMS of the Invention This invention concerns a process for the manufacture of flexible polyurethane foams from urethane-modified aromatic polyisocyanates having an NCO content of 15 to 30 percent by weight and a viscosity of 100 to 2000 centipoises at 20.degree.C, which are obtained by reaction of a mixture of diphenylmethane diisocyanates and polyphenylene polymethylene polyisocyanates containing 55 to 85 percent by weight of diphenylmethane diisocyanate based on the total weight of the polyisocyanate mixture and a hydroxyl compound with 2 to 4 Zerewitinoff active hydrogen atoms and a molecular weight of 60 to 1500, in an equivalency ratio of NCO groups to active hydrogen atoms of the hydroxyl compound of 2:1 to 60:1, polyols, catalysts, blowing agents, and optionally, chain extenders, auxiliaries, and additives.

Abstract: A PROCESS FOR THE PREPARATION OF FLEXIBLE POLYURETHANE FOAMS EMPLOYING POLYESTER-POLYETHER POLYOL MIXTURES of the Invention The invention concerns a process for the preparation of flexible polyurethane foams having good hydrolytic stability, improved damping, with equal or higher levels of other physical properties and with a high absorption capacity. The foams are prepared by reacting organic polyisocyanates and mixtures of (a) liquid polyester polyols, which are produced by the polycondensation of organic dicarboxcylic acid and a polyol mixture which contains 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, and at least one triol, and (b) di- to tetra-functional polyether polyols having molecular weights of 1500 to 6000 in the presence of catalysts and blowing agents as well as optionally chain extenders, auxiliaries, and additives.

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: To prepare light-stable polyurethane integral skin foams, especially soft integral foams, aliphatic and/or cycloaliphatic polyisocyanates, both categories preferably containing urethane groups and/or biuret groups, are reacted with polyols in the presence of blowing agents and of a synergistic catalyst combination comprising an alkali metal hydroxide, alkali metal alcoholate, alkali metal phenolate, alkali metal salt of a weak acid and/or hexahydrotriazine derivative and an organic tin, zinc and/or iron(II) compound, in the presence or absence of assistants and adjuvants. The preferred catalyst combination is tri-(dimethylaminopropyl)-s-hexahydrotriazine and dibutyl-tin dilaurate.
