Abstract: Paper fibres are bonded in absence of metallic salts at pH 5-9 pref. 6-8 using anionic polymer dispersions by polymsn. with a hydrophobic monomer in aq. medium in presence of emulsifiers contng. COOH gps., where the dispersions contain particles of mean size 200 nm and having Tg. 70 degrees C. Monomers are e.g. (meth)acrylic acid esters with >3C alcohols, or vinyl aromatic cpds. Emulsifiers are salts of (iso) fatty acids or resinic acids and their hydrogenation/disproportionation products or ethylene or diene reacted with maleic acid derivs. The process prevents growth of algae and deposits of adhesive and foaming. Corrosion is also reduced because the soln. is at near neutral pH in absence of salts.

Abstract: A process for removing anionic compounds from water which is recycled in manufacturing processes, and from waste water, by adding (1) water-soluble products obtained by reacting an alkylating agent, having an aromatic substituent, with a cationic polyelectrolyte and (2) mineral adsorbents and/or a magnesium salt, aluminum salt or iron salt, with formation and flocculation of water-insoluble reaction products.

Abstract: In prodn of colloidal solns by reacting melamine with HCHO (source) in aq. medium, treating the precondensate with further HCHO and ageing at pH 5, precondensation and futher-HCHO treatment are both at pH 4.9 and the obtd suspension is acidified with HCl and/or H3PO4. The obtd. colloidal solns have particles of low charge; mass ratio and give a strong hydrophilic effect to paper (after addn. to pulp). They are storage-stable for >6 months.
