Abstract: 1362529 Acrylic fibres ASAHI KASEI KOGYO KK 24 Sept 1971 [26 Sept 1970] 44640/71 Heading C3P Acrylonitrile polymer fibres comprise a cross-linked copolymer derived from (1) acrylonitrile, (2) at least 0À5% by weight of a monomer of the formula  wherein R 1  is H, halogen, C 1 -C 18  alkyl, -CH 2 Cl, -CH 2 COOR (in which R is C 1 -C 18  alkyl or -C 2 H 4 Cl or -C 2 H 4 CN), or -COOR (in which R is C 1 -C 18  alkyl or -C 2 H 4 Cl); R 2  is H, C 1 -C 18  alkyl, -CH 2 R (in which R is C 1 -C 18  alkoxy, halogen, -OH, -CN or -SO 3 H), -CH 2 COOR (in which R is C 1 -C 18  alkyl), -CO-R (in which R is C 1 -C 18  alkyl), or phenyl (the R 2  substituents in  being the same or different); and a is an integer of 1 to 100, and (3) at least 0À5% by weight of a monomer of the formula wherein R 3  and R 4  are as defined above for R 1  and R 2  respectively (the R 4  substituents in being the same or different); R 5  and R 6  which may be the same or different are H, C 1 -C 18  alkyl, -OR (in which R is C 1 -C 18  alkyl or -CH 2 Cl), -CH 2 COOR (in which R is C 1 -C 18  alkyl), benzyloxy, halobenzyloxy, halophenoxy or -OH, or a salt of the phosphoric or phosphonic acid group formed when R 5  and/or R 6  is -OH; and (b) is an integer of 1 to 105, the total amount of components (2) and (3) being not more than 50% by weight of the copolymer. The copolymer may additionally be derived from 0À1 to 10% by weight of at least one other comonomer, e.g. an alkyl acrylate or methacrylate, dimethyl or diethyl itaconate, acrylic, methacrylic, itaconic or maleic acid or a salt or amide thereof, an alpha-substituted acrylonitrile (substituent being chlorine, alkyl, cyano or phenyl), vinyl or vinylidene chloride, styrene, vinyl acetate, an ethylenically unsaturated sulphonic acid or salt thereof, a vinylpyridine, or vinylpyrrolidone. The copolymer may, if desired, be blended with a conventional acrylonitrile polymer or copolymer, e.g. an acrylonitrile/methyl acrylate copolymer or an acrylonitrile/vinyl acetate/sodium styrenesulphonate copolymer. The fibres can be obtained by dissolving the defined copolymer, or copolymer blend, in a suitable solvent, spinning the resultant solution into a coagulation bath, washing the filament so formed in water, and then stretching, drying and cross-linking the copolymer filament at 80‹ to 170‹ C. If desired, a further dry-heat treatment at a higher temperature may be effected to increase the degree of cross-linking. The copolymers used in forming the fibres can be obtained by polymerizing the corresponding monomers by bulk, solution, suspension, emulsion or precipitation methods, generally in the presence of a conventional free radical initiator, or by irradiation, e.g. with electron beams or ultra-violet rays. Polymerization may be effected continuously, semi-continuously or batchwise.

Specified are polyhydric alcohols-ethylene glycol, propylene glycol, 1 : 2-butanediol, 2 : 5-pentanediol, 1 : 6-hexanediol, neopentyl glycol, polyethylene glycols, polypropylene glycols, glycerol, erythritol, pentaerythritol, polypentaerythritol, sorbitol, mannittol, polyallyl alcohols, trimethylol ethane, tetramethylol cyclohexanol and mixtures of ethylene glycol and glycerol or trimethylol ethane; polycarboxylic acids-succinic, malonic, adipic, azelaic, sebacic, maleic, fumaric, dimerized fatty, aconitic, phthalic, isophthalic and terephthalic acids; aldehydes-formaldehyde, paraformaldehyde, trioxymethylene, hexamethylene tetramine, butyl formal, acetaldehyde, propionaldehyde, n-butyraldehyde, isobutyraldehyde, capronaldehyde, valeraldehyde, heptaldehyde and furfural.  Reaction of the polyester and aldehyde may be effected at 40-60 DEG  C. in the presence of an acid or alkaline catalyst. Coating compositions are made by dissolving the resins in a solvent, e.g. an aromatic hydrocarbon, naphtha, butyl, "Cellosolve" (Registered Trade Mark) or diacetone alcohol and possibly adding phosphoric acid or the polyoxyethylene ester of a fatty acid.ALSO:Metals are coated with a resin made by reacting an aldehyde with a polyester produced from (a) a polycarboxylic acid or anhydride, (b) a polyhydric alcohol, (c) a bis(hydroxyaryl) pentanoic acid of formula:  <FORM:1011838/B1-B2/1> where R is chlorine, bromine or lower alkyl and n is 0, 1 or 2, the hydroxyl groups being attached to the 4-position of the ring when n is 0, and, possibly (4) a saturated or unsaturated aliphatic monocarboxylic acid containing 9-22 carbon atoms.  The resin is preferably applied to the metal in the form of a solution (e.g. in an aromatic hydrocarbon, butyl "Cellosolve" (Registered Trade Mark) or diacetone alcohol) and the solution may also contain phosphoric acid or a polyoxyethylene ester of a fatty acid.  After application, the coating is baked at 300-425 DEG F. for 5-60 minutes.  The coatings are especially useful as interior coatings for metal cans.  Examples describe the coating of tin plate.
