    Abstract: A composition suitable for treating cellulosic fabrics comprises a compound which improves the crease resistance of the fabric and a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide or an ether derivative thereof and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5 - triacyl - hexahydrotriazine - (1,3,5) allyl acrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinyl-pyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diureine, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetal, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The composition may be in the form of an aqueous solution or dispersion containing 30-150 g./l. of the crease-resisting agent and 5-100 g./l. of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants, colouring pigments and an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, mono-ammonium phosphate, ammonium nitrate and ammonium acetate. ALSO: The tendency of crease proofed cellulosic fabrics to become irreversibly soiled during washing with hot aqueous liquids is reduced by effecting the crease-proofing by a process comprising treating them with a compound which improves the crease resistance of the fabric and with a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane, diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5- triacryl-hexahydrotriazine- (1, 3, 5) allylacrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinylpyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diurein, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetol, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The crease resisting agent and copolymer may be applied from an aqueous solution or dispersion containing 30-150 g/1 of the crease resisting agent and 5-100 g/1 of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants or colouring pigments. Alternatively the crease resisting agent and the copolymer may be applied successively in any sequence. The treating agents may be fixed on the fabrics by the action of an elevated temperature and/or an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, monoammonium phosphate ammonium nitrate and ammonium acetate. After impregnation and prior to heating the fabric may be calendered on a Schreiner calender. Fabrics comprising cotton, linen, or viscose rayon fibres alone or in admixture with polyamide, polyester, cellulose ester or acrylonitrile polymer fibres may be treated.

    Abstract: Polyurethane foams are prepared by reaction of polyisocyanates with hydroxyl-containing polyesters or polyethers, in the presence of water or a volatile organic blowing agent boiling between 0 DEG and 100 DEG C., together with at least one copolymer containing both tertiary nitrogen, and isocyanate-reactive groups (i.e. carboxylic, carboxylic amide, mercapto, thiolic, thionic, sulphydryl, primary or secondary basic amino, carbon bonded activated hydrogen, or preferably hydroxyl groups), the copolymer being obtained by polymerizing a ,b -ethylenically unsaturated monomers (i.e. compounds having a polymerizable double bond between the first two carbons of the unsubstituted end of the carbon chain). Suitable copolymers are polymerization products of either a monomer having one of the above-mentioned required groups with a second monomer having the other required group, or a monomer having both required groups with another a ,b -unsaturated monomer. Examples are given for preparation of such polymers from the following, using azodibutyronitrile as a catalyst in all cases: (1) isobutyl acrylate, 4-hydroxy butyl acrylate, tertiary dodecyl mercaptan, and N-vinyl imidazole; (2) isobutyl acrylate, 4-hydroxy butyl acrylate, tertiary dodecyl mercaptan, and N - vinyl - 2 - methylol imidazole; (3) butyl acrylate, 4-hydroxybutyl acrylate, tertiary dodecyl mercaptan, and dimethylamino styrene; (4) butyl acrylate, 4-hydroxy butyl acrylate, tertiary dodecyl mercaptan, butene-2 ol (1), and N vinyl imidazole; (5) butyl acrylate, 4 hydroxy butyl acrylate, tertiary dodecyl mercaptan, and N vinyl 2,4,5 trimethyl imidazole; (6) 2 ethyl hexyl acrylate, 4 hydroxy butyl acrylate, tertiary dodecyl mercaptan, butenol, and vinyl imidazole; (7) isobutyl acrylate, 2 hydroxy propyl methacrylate, tertiary dodecyl mercaptan, and 2 methyl 5 vinyl pyridine; (8) butyl acrylate, 2 hydroxy ethyl acrylate, butenol, and N vinyl benzimidazole (9) butyl acrylate, butene 2 ol (1), and 2; hydroxyethyl N vinyl imidazole; (10) butyl acrylate, 4 hydroxy butyl acrylate, vinyl propionate, butene 2 ol (1), and N vinyl 3,5 dimethyl pyrazole; (11) 2 ethyl hexyl acrylate, 4 hydroxy butyl acrylate, hexene (3) diol-2,5, styrene, and N-vinyl-2-methyl imidazole; (12) butyl acrylate, 2-hydroxy propyl acrylate, butene - 2 - ol - (1), vinylidene chloride, and N-vinyl imidazole; (13) isobutyl acrylate, butene-2-ol-(1), and di-(b -hydroxyethyl)-aminomethylene methacrylamide; (14) butyl acrylate, butanediol monoacrylate, secondary butenol, and N-vinyl imidazole. These co-polymers suitably comprise 5 to 25% of the isocyanate-reactive mixture, in which the remaining components are conventional polyesters or polyethers useful in polyurethane production. Optional additives to the condensation reaction mixture are, e.g., emulsifiers, foam stabilizers to regulate pore size, such as organopolysiloxanes, and catalysts, such as tin compounds and tertiary amines. The polyurethanes of the invention may be prepared by one-shot techniques, and the process obviates the use of toxic or odiferous tertiary amine catalysts, since the copolymers have corresponding catalytic activity and then become part of the final polymer mass by cross-linking.
