    Abstract: Bonded nonwovens can be produced with particular advantage by the wet method by treating the textile fibers prior to the addition of the binder polymers with water-soluble cationic polycondensation products which have been prepared from carbamides, formaldehyde, dicyanodiamide and salts of ammonia or of amines.

    Abstract: 1,174,159. Polymer composition. BADISCHE ANILIN- & SODA-FABRIK A.G. 31 March, 1967 [2 April, 1966], No. 14720/67. Heading C3P. A caulking and sealing compound contains (a) 1 part by weight of an emulsion polymer A of an ester of an ethylenically unsaturated carboxylic acid having 3 to 5 carbon atoms and a monohydric aliphatic alcohol having 1 to 12 carbon atoms, said polymer being in the form of an at least 50% aqueous dispersion, (b) 0À25 to 2À5 parts of a practically anhydrous and solvent free emulsifiable polymer B which (b 1 ) has a K value of 10 to 70 and is a polymer of an ester of acrylic and/or methacrylic acid and a monohydric alphatic alcohol having 2 to 8 carbon atoms and/or of a vinyl alkyl ether having 1 to 4 carbon atoms in the alkyl radical and/or of butadiene or (b 2 ) has a K value of 5 to 40 and is a polymer of isobutylene and/or isoprene, (c) 0À5 to 2À5 times the weight of the polymers of conventional inorganic fillers and (d) 8 to 18% by weight of the composition of water. The composition may also contain an emulsifier, a protective colloid and 0À5 to 10% by weight of A and B of a urea-formaldehyde resin, which is preferably modified with a bisulphite. Suitable polymers A include copolymers of (i) nbutyl acrylate and acrylonitrile or methyl acrylate, (ii) decyl acrylate, methyl methacrylate and acrylic acid, (iii) 2-ethylhexyl acrylate, styrene and acrylic acid, (iv) 2-ethylhexyl acrylate and vinyl chloride, (v) 2-ethylhexyl acrylate, acrylonitrile, and/or methacrylonitrile, and acrylic acid and/or methacrylic acid and (vi) n-butyl acrylate, methyl acrylate and acrylic acid. Polymer B is, e.g. a copolymer of one of the specified esters with acrylonitrile and/or methacrylonitrile and/or acrylic or methacrylic acid, polyvinyl isobutyl ether, polyvinyl methyl ether, an oily butadiene homopolymer or copolymer with styrene and/or alpha-methyl styrene and/or isobutylene, polyisobutylene or an isobutylene-styrene copolymer. In Examples 1 to 10 polymer A is a 2- ethylhexylacrylate/acrylonitrile/acrylic acid terpolymer, which is compounded with (1) to (3) polyisobutylene or poly-(n-butyl acrylate), a sperm oil fatty alcohol-ethylene oxide condensate, asbestos and chalk; (4) polyisobutylene, the said condensate, quartz, talc and carbon black; (5) and (6) poly-(vinyl isobutyl ether) and (5) an isooctyl phenol-ethylene oxide condensate, chalk and quartz or (6) ethylene glycol, quartz, chalk, carbon black, talc and heavy spar; (7) and (8) a polybutadiene oil modified with maleic anhydride, the said sperm oil condensate, a lead drier and quartz; (9) and (10) a polybutadiene oil isomerized in the presence of iron carbonyl, the sperm oil condensate and (9) chalk and quartz or (10) chalk alone. The compositions in the other examples comprise (11) A-a vinyl propionate t.-butyl acrylate/ acrylamide copolymer and B-a copolymer of n-butyl acrylate and vinyl isobutyl ether; (12) A-an n-butyl acrylate/styrene/acrylic acid copolymer and B-a 2-ethylhexyl acrylate/ acrylonitrile/butanediol monoacrylate copolymer; (13) A-an ethyl acrylate/acrylic acid copolymer and B-poly-(n-butyl acrylate); (14) A-an n-butyl acrylate/acrylonitrile/butanediol monoacrylate / N - methylol methacrylamide/ acrylic acid copolymer and B-poly-(vinyl iso. butyl ether); (15) A-an n-butyl acrylate/ methyl acrylate/acrylic acid copolymer and B-poly-(n-butyl acrylate) and (16)A-an nbutyl acrylate/vinylidene chloride/acrylic acid copolymer and B-poly-(vinyl isobutyl ether). The other ingredients of Examples 11 to 16 are one of the aforesaid ethylene oxide condensates, chalk, and in some cases, quartz.

    Abstract: 1292499 Adhesive coatings BADISCHE ANILIN- & SODA-FABRIK AG 5 March 1970 [6 March 1969] 10572/70 Heading B2E Pressure-sensitive adhesive coated articles have at least one adhesive coating containing a copolymer of (a) from 50 to 90% by weight of acrylic and/or methacrylic esters of primary and/or secondary alkanols of 4 to 12 carbon atoms, of which at least 25% are derived from alkanols having 6 to 12 carbon atoms, (b) from 10 to 40% by weight of acrylic and/or methacrylic esters of tertiary alcohols of 4 to 12 carbon' atoms and (c) from 3 to 12% by weight of polymerizable heterocyclic N-vinyl compounds and/or other olefin comonomers containing reactive groups. Suitable primary and secondary alkanols for the esters are nbutanol, s-butanol, n-hexanol, n-octanol, 2- ethylhexanol-1 alcohol, n-decanol and n-dodecanol. Suitable tertiary alkanols are t-butanol, 2-ethylhexanol-2 or 2-ethyl decyl alcohol. Suitable N-vinyl compounds are N-vinyl caprolactam, N-vinyl imidazole and N-vinyl 1 pyrrolidone. Other suitable comonomers are acrylic acid, methacrylic acid, acrylomide, methacrylomide, N - methylacrylomide, N - methylol acrylomide, N - methalol methacrylomide, N - methoxy methacrylomide, N - n - butoxy methacrylomide, maleic acid, itaconic acid and fumaric acid and their amides, and crotonic acid and its amide. Other suitable monomers, containing hydroxyl groups are specified. The substrate may be sodium paper, metal foils, such as of aluminium, films of polyethylene, polyvinyl chloride, polystyrene and polyethylene terephthalate, foamed materials such as of rubber, polyvinyl chloride, polystyrene, polyurethane and polyether and woven and non-woven webs of fibrous material such as woven textile fabrics and non-woven fabrics of natural and/or synthetic fibres.
