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: Mixt. of useful in textile reviving compsns. consists of (a) 1 part amine oxide of formula R'CONH-(CH2)n-NR2R3 right arrow O (1) (where R1 is satd. or ethylenically unsatd. opt. OH-substd. 15-17C aliphatic gP. R2 and R3 are 1-3C aliphatic gps. and n is integer 2 to 5) and (b) 1-2 parts solvent of formula R4O(CHR5CHR6O)mH (II) where R4 is H or 1-4C alkyl, and R5 and R6 are H or Me, provided at least one is H, and m is 1 or 2). Mixt. is pref. used as an aq. soln. pref. contg. 15-25 wt. % (I) and 20-40 wt. % (II). Used for softening and anti-electrostatic finishing of textile fibres and fabrics, esp. acrylonitrile polymers but also polyesters and cotton. (I) and (II) are miscible with water in all proportions, conc. solns. are stable to storage and only need diluting with cold water, both anti-electrostatic and reviving effects are excellent.

Abstract: Title cpds. of formula (I): (where R1 is opt. branched 1-6C alkyl opt. substd. by OH gps, or two R1 gps. together with the N atom form a 4-7C heterocycle; R2-R4 are each a cyclic, linear or branched, satd. or contg. an olefinic link 1-30C alkyl, opt. substd. by OH gps. and opt. interrupted by ether bridges, or a phenyl or benzyl gp. opt. substd. by Cl or 1-12C alkyl; R3 and R4 may also represent H or a pair of free electrons; R5 is H or 1-4C alkyl; Z is 2-6C alkylene, opt. substd. esp. by OH gps. or interrupted by either or ester gps; X- is an (in)organice anion; and these various anions may be the same or different; n is a whole no. 1-3), are prepd. by quaternising the corresp. unguaternised cpd. They are effective in amts. of 0.003-1.5 wt. % w.r.t. anionic polyacrylonitrile fibres.

Abstract: Polyetheramine are prepd. by condensing di- or polyamines (I) contg. 2-10 N atoms wich chlorohydrin ethers (II) prepd. from 1 mol divalent 2-5C alcohol, the ethoxylated adduct contg. up to 18 ethylene oxide units, glycerol or polyglycerol contg. up to 15 glycerol units and 2-8 mol epichlorohydrin at 110-200 degrees C in polar, water miscile solvents in the absence or extensive exclusion of water, adding an alkali(ne earth) metal base to neutralise >=20% of the HCl formed by the condensn. and post-condensing (I) is used in an amt. of 0.6-2.5 mol per mol. chlorohydrin gp. in (II). The aids are prepd. withou the necessity of having to graft components used during the condensn. with ethylene imine.
