Abstract: Water-sol., cross-linked, nitrogenous condensation prods. (I), the viscosity of which in aq. soln. increases with increase in temp. and falls again with decrease in temp., are prepd. by reacting (a) 0.8-30 pts. of a block copolymer of formula R-O-(CH2CH2O)x-(CH2CH(CH3)O)y-(CH2CH2O)x-R (II), in which R is H(OCH2C(CH2Cl)H-)n, with n = 0.75-3, -COCl or -CH2CH2Cl, x = 50-250, y = 20-100, and x:y = 6.5:1-1:15, with (b) 1 pt. of a cpd. with is not 4 basic NH gps. Reaction is in a polar solvent at 20 180 degrees C. (I) are used as additives in etching, polishing and de-metallisation baths. The surface of the treated metal is improved. Etching baths contg. H2SO4-H2O2 are more easily handled. In electrochemical polishing and burr-removal, (I) may (partly) replace H3PO4; disposal of waste water is then easier. The polishing and smoothing effect can be controlled by varying the temp. In de-metallisation, e.g. in removal of Cu, Ni, Cr, Zn, noble metals and alloys from substrates such as steel, brass, Zn castings or Al, addn. of (I) protects the substrate and regulates the attack by the soln. on increase in temp.

Abstract: A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte. The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.

Abstract: Prodn. of N-(2-sulphoarylmethyl)-pyridinium-betaines of formula (I), (where X is an acid anion; and each R1 and R2 is H, aliphatic gp. or alkoxy, and R1 can each also be halogen and each R2 can also represent an aromatic ring annellated on the pyridine ring), comprises reacting an N-(aryl-methyl)- pyridinium salt of formula (II) with SO3 in the presence of H2SO4 and/or H3PO4. (I) are intermediates in the prepn. of dyestuffs and pesticides. (I) are also polishing and levelling agents for galvanic baths esp. acid galvanic Ni baths. (I) are good levelling agents in both high current density regions and low current density regions, without having too strong a negative effect on the macrodispersibility. (I) can be used in combination with other Ni polishers. (I) can be used as additives in the corrosion protection of steel, brass, Zn, Al alloys and Mg alloys and to give shiny, hard, very ductile and smooth Ni-coatings. (I) can also be used as a levelling agent in dyeing anionic modified polyacrylonitrile fibres. (I) are obtd. in good yields and purity by a simple and economic method.
