Abstract

1384771 Polyurethane foams BAYER AG 26 Jan 1972 [27 Jan 1971] 3672/72 Heading C3R Fireproof, non-shrinking, open-pored elastic or semi-elastic polyurethane foams are prepared from (1) polyethers of M.W. 750 to 16,000 containing at least two active hydrogen atoms and in which at least 10% of their OH groups are primary, (2) polyisocyanates, (3) water and/or organic blowing agents, (4) catalysts, (5) emulsifiers, and (6) 0À2 to 6% by weight (based on the polyether) of a polyalkylene polyamine auxiliary agent of the Formula (I) wherein R denotes -CH 2 CH 2 -, -CH 2 CH 2 CH 2 - or -CH 2 CH 2 CH 2 CH 2 -, R 1 denotes H, -CH 3 , -C 2 H 5 , -C 3 H 7 , -C 4 H 9 or -(R-NHR 2 ), R 2 denotes H, -CH 3 , -C 2 H 5 , -C 3 H 7 , -C 4 H 9 or -CH 2 CH(OH 3 )NH 2 , and R 3 denotes H, -CH 3 , -C 2 H 5 , -C 3 H 7 , -C 4 H 9 or -CH 2 CH 2 OH; or of the Formula (II) or -CH 2 CH 2 CH 2 CH 2 CH 2 CH 2 -, and R<SP>1</SP> 2 denotes H, -CH 3 , -C 2 H 5 , -C 3 H 7 , -C 4 H 9 or -CH 2 CH 2 NH 2 ; and/or 0À25 to 15% by weight (based on the polyether), of a hydroxyalkylene amine auxiliary agent of the formulae wherein R<SP>11</SP> denotes H, C 1-4 alkyl or C 7-20 alkylaryl, R<SP>11</SP> 1 denotes H, C 1-20 alkyl, C 5-14 cycloalkyl, C 6-14 aryl, C 7-20 alkylaryl or oleyl, R<SP>11</SP> 2 denotes H or OH, n is 2 to 6, m 1 , m 2 and m 3 are integers of from 1 to 5; or products of addition of epoxides and hydroxyalkylene amines of the above formulae in which products a maximum of 3 mols of epoxide have been added per active hydrogen atom of the hydroxyalkylene amines. In examples specified polyethers are ethylene oxide modified polypropylene glycols obtained by condensing propylene oxide with trimethylolpropane, sorbitol, propylene glycol, dipropylene glycol, glycerol, hexanetriol or dihydroxydiphenylmethane; specified poly-isocyanates are mixtures of monomeric and polymeric toluene diisocyanate, mixtures of toluene diisocyanate and polyphenyl poly. methylene polyisocyanate, adducts of toluene diisocyanate and trimethylolpropane, biuret polyisocyanates prepared from toluene diisocyanate and water, mixtures of allophanate polyisocyanates and toluene diisocyanate formed by reacting toluene diisocyanate with trimethylopropane and optionally further reacting the product with 2,3-dibromopropanol-1, mixtures of toluene diisocyanate and toluene diisocyanate trimer modified with tripropylene glycol or trimethylolpropane and optionally further modified with 2,3-dibromopropanol, mixtures of monomeric toluene diisocyanate and the trimerized reaction products of toluene diisocyanate and 1,2-propyleneglycol optionally further modified with tripropylene glycol or 2,3-dibromopropanol-1, and mixtures of toluene diisocyanate with trimerized reaction products of 1,2-propylene glycol and mixtures of toluene diisocyanate; and 4, 4<SP>1</SP>-diphenylmethane diisocyanate; and specified catalysts are endoethylenepiperazine in optional combination with N-ethyl morpholine, triethylamine, pentamethyl diethylenetriamine or dimethylphenylethylamine.
