Abstract

A process for the manufacture of foamed cellular materials by interaction in one or more stages of organic polyisocyanates with hydroxyl group-containing polymers and, as necessary, water and/or catalysts, is characterized in that there is incorporated in the reaction mixture from which the foam is made a block copolymer which contains at least one isocyanate-reactive group per molecule and which is a block copolymer of ethylene oxide and a cyclic oxide which when homopolymerized produces a hydrophobic chain. The hydrophobic chain-producing cyclic oxide may be, for example, 1:2-propylene oxide, 1:2- or 1:3-butylene oxide, tetrahydrofuran or oxacyclobutane. The initiator for the block copolymer may be water, diethylene glycol, iso-octanol, diethylene glycol monoethyl ether, isopropanol, phenol, sec. butanol, a monocarboxylic acid, a secondary amine such as methylaniline or cetylethylamine, glycerol, trimethylol-ethane or propane, triethanolamine, diethanolamine, pentaerythritol and sorbitol. Catalysts for the foam-forming reactions are tertiary amines, other basic materials such as potassium acetate and non-basic metallic compounds such as ferric acetyl acetonate. The block copolymer may be dissolved in one of the reactants or added as a solution in, for example, tri(b -chlorethyl) phosphate. There may also be added pigments, plasticizers, surface-active agents, litharge and barium oxide. In typical examples foams are obtained by reacting (1) a polyester from pentaerythritol, 1:3-butylene glycol, adipic acid and phthalic anhydride; b -trichlorethyl phosphate; water; an octylcresol/alkylene oxide condensation product and a 4:41-diisocyanato-3-methyldiphenyl methane composition (containing some triisocyanate) with which a block copolymer of a propylene oxide and ethylene oxide has been incorporated; (14) a prepolymer from polypropylene glycol and 2:4- and 2:6-toluene diisocyanates; octylcresol/ethylene oxide condensate; dimethylcyclohexylamine; a block copolymer of ethylene oxide with an oxypropylated diethylene glycol monoethyl ether; and water. Specifications 731,603 and 825,896 are referred to.ALSO:A process for the manufacture of foamed cellular materials by interaction in one or more stages of organic polyisocyanates with hydroxyl group-containing polymers and, as necessary, water and/or catalysts, is characterized in that there is incorporated in the reaction mixture from which the foam is made a block copolymer which contains at least one isocyanate-reactive group per molecule and which is a block copolymer of ethylene oxide and a cyclic oxide which when homopolymerized produces a hydrophobic chain.
