    Abstract: In an aqueous acidic plating bath for the electrolytic deposition of zinc, which contains conventional conductive salts, brighteners and surfactants, one of the surfactants is a surfactant of the formula I where R1 is C4-C20-alkyl, R2 is identical to R1 or is hydrogen, X and Y are each a radical -SO3H, where the hydrogen atom can be replaced by an alkali metal or alkaline earth metal atom or by one equivalent of zinc and n is an integer from 5 to 50.

    Abstract: 1431476 Antistatic fabric BASF AG 20 Sept 1973 [21 Sept 1972] 44160/73 Heading DIP Antistatic finish is formed on synthetic fibres by fixing on the surface of the fibres a compound containing antistatically active groups, wherein a compound of formula I A is n-butylene, B is -(CH2)2 or -CH.CH3. CH2- R is H or C1-6 aliphatic, R' is alkylene 1=5-100 m=0-30, n 1-4or if R is C2H4, 1-20 and z=1-10, is allowed to react on the fibre with a compound of formula II wherein B has the meaning above, P is 6-30, R is 2- to 6-valent C3-13 aliphatic or cycloaliphatic, #R is CH2-CHOH-CH2Cl or -CH2-#CHCH2O and q is 2-6.The compounds may be partially reacted prior to application to the fibres, preferably to a degree in which the compounds are still soluble in water. The compounds may be applied by dipping, spraying, spreading or pouring. The compounds may be fixed by heating up to 200‹C. The fibres being treated may be polyethylene, polypropylene, vinyl chloride or vinylidene chloride polymers, polyurethanes, polyesters, acrylonitrile homopolymers and copolymers and polyamides and may be in the form of woven, knitted or non-woven fabrics.

    Abstract: Copolymers of (A) 5 to 95 mol % of ethylenically unsaturated monocarboxylic acids or dicarboxylic acids with 3 to 10 C-atoms, their anhydrides, their alkali metal salts, alkaline earth metal salts or ammonium salts or mixtures thereof; (B) 5 to 95 mol % of ethylenically unsaturated acetals, cetals or orthocarboxylic acid esters of the general formula (I), in which the variables have the following meanings: R to R are, independently of each other, hydrogen or an organic radical and a to d are, independently of each other, 0 or 1; and (C) 0 to 70 mol % of other copolymerisable monomers. The invention relates to the use of aqueous solutions or dispersions of said copolymers or hydrolysis products or polymeric analogous reaction products of said copolymers as tanning agents for single tannage, pre-tannage and co-tannage of dehaired skins and hides, and retannage of leather and skins.

    Abstract: The invention relates to a process for preparing self-releasing, compact or cellular moulded bodies optionally containing reinforcing agents and made of polyisocyanate polyaddition products by reacting a) organic and/or modified organic polyisocyanates with b) at least one compound with at least two reactive hydrogen atoms and a molecular weight of 500 to 9,000 and optionally c) chain extension and/or cross-linking agents in the presence of d) alkyl and/or alkenyl succinic acid monoamides, -monoamides, poly(alkyl succinic acid)- and/or poly(alkenyl succinic acid)-polyamides, -polyimides, -monoamide monoimides, -polyamide imides, -amide polyimides and- polyamide polyimides or mixtures thereof as internal mould release agents, and also in the presence or absence of e) catalysts, f) blowing agents, g) reinforcing agents, h) auxiliary agents, in an open or closed moulding tool, optionally under compression. The invention also relates to the use of alkyl- and/or alkenyl succinic acid amides and/or imides (d) as internal mould release agents for the preparation of moulded bodies made of polyisocyanate polyaddition products.
