    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: Textile nonwovens can be prepared with particular advantage by treatment of textile fibers suspended in an aqueous medium with dissolved quaternary organic ammonium salts and with watersoluble salts of polymers having carboxyl groups of vinylpyrrolidone polymers, precipitation of binder polymers dispersed in water onto the treated suspended fibers, separation of the aqueous medium from the fibers and drying the bonded fibers.

    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.
