Abstract

A process for the manufacture of rigid or semirigid foamed polymeric products comprises reacting 100 parts by weight of a monomeric organic polyisocyanate with between 1 and 30 parts by weight of water in the presence of between 5 and 200 parts by weight of a non-ionic surface-active agent that is at least partially miscible with water and between 0,1 and 30 parts by weight of a catalyst for the reactions of organic polyisocyanates. Preferably the reaction mixture also contains 5 to 30 parts by weight of a compound containing two or more isocyanatereactive groups, such as trimethylopropane, ethyl cellulose, and hydroxyl-ended polyesters and polyethers. Suitable catalysts are tertiary amines and their salts; complexes of a b -diketone with manganese, thorium, titanium or zirconium; dibutyl tin dilaurate; basic inorganic compounds and basic alkali metal salts of weak acids. Surface-active agents specified are reaction products of ethylene oxide with aliphatic alcohols containing 12 to 22 carbon atoms per molecule or with alkyl phenols containing 6 to 12 carbon atoms in the alkyl groups. Pigments, flameproofing agents and fillers may be incorporated in the products. In typical examples foamed products are prepared from mixtures of (5) tri-b -chloroethyl phosphate, tris-2:4-pentane diono manganese III, water, an octyl-cresol/ethylene oxide reaction product and a diphenylmethane diisocyanate composition prepared from a crude diamine containing some polyamine; (10) 25 parts of a polyester (from pentaerythritol, 1:3-butylene glycol, adipic acid and phthalic anhydride), 7,5 parts of ethylene oxide/octyl cresol condensate, 10 parts water, 7,5 parts potassium acetate and 120 parts of the diphenylmethane diisocyanate composition as before. The foams are useful for packaging and as thermal insulation.ALSO:A process for the manufacture of rigid or semi-rigid foamed polymeric products comprises reacting 100 parts by weight of a monomeric organic polyisocyanate with between 1 and 30 parts by weight of water in the presence of between 5 and 200 parts by weight of a nonionic surface-active agent that is at least partially miscible with water and between 0,1 and 30 parts by weight of a catalyst for the reactions of organic polyisocyanates.
