Abstract

1,184,807. Polyanionic polymer/polycationic polymer salt compositions. AMERICAN CYANAMID CO. 21 March, 1967 [29 April, 1966], No. 13263/67. Headings C3H, C3P, C3R and C3U. [Also in Division D2] Compositions suitable for use in the manufacture of paper of improved dry strength comprise an aqueous solution of a composition of (a) an ionically self-crosslinked coacervating liquid ampholytic polysalt of a water-soluble polyanionic polymer with a water-soluble polycationic polymer in a weight ratio of from 95 : 5 to 5 : 95, at least one of said polymers being a weak electrolyte and having an ionization constant less than 10<SP>-3</SP>, with (b) sufficient of a water-soluble ionization suppressor (i.e. a water-soluble monomeric compound having an ionization constant greater than 10<SP>-6</SP>) to render said polysalt water-soluble. The ionization suppressor may be, for example, an alkali metal hydroxide, ammonium hydroxide or a quaternary ammonium hydroxide, a mineral acid or formic, acetic or a chloroacetic acid, or a water-soluble salt of such acids. The compositions may include a fixing agent for cellulose fibres, e.g. an aluminium, ferric, eerie or zirconium salt, e.g. a sulphate, chloride, acetate, benzoate or nitrate, the preferred salt being alum. In examples the polysalts are derived from the following as anionic polymers: acrylamide-acrylic acid copolymer, acrylamidestyrene-maleic anhydride copolymer, casein (sodium salt), acrylamide-allyl sulphonic acid copolymer, poly-(sulphomethyleneacrylamide), sulphonated polystyrene; and from the following as cationic polymers: adipic acid-tetraethylenepentamine-epichlorohydrin resin condensation product, methylamine-ammonia-epichlorohydrin resin condensation product, diethylenetriamine-epichlorohydrin resin condensation product, the product obtained by heating polyacrylamide with ethylene diamine, acrylamide-dimethylpyridine copolymer quaternized with dimethyl sulphate, acrylamideacrylic acid-diallyl dimethyl ammonium chioride copolymer, poly-(vinylbenzyl trimethyl ammonium chloride), poly-(diethylaminoethyl acrylate), ), polyethyleneimine, water-soluble cationic starch.
