    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.

    Abstract: PCT No. PCT/EP95/04576 Sec. 371 Date May 23, 1997 Sec. 102(e) Date May 23, 1997 PCT Filed Nov. 21, 1995 PCT Pub. No. WO96/02597 PCT Pub. Date Feb. 1, 1996A process for coating or printing substrates with a coating or printing composition comprises applying a polymerizable material containing liquid-crystalline, polymerizable monomers which carry at least two polymerizable groups for coating and at least one polymerizable group for printing, to the substrate, and subsequently carrying out the polymerization, where the coating composition or the printing composition comprises a1) a chiral liquid-crystalline monomer and b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), or the coating composition or the printing composition comprises a2) an achiral liquid-crystalline monomer, b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), and c) a non-liquid-crystalline chiral compound.

    Abstract: Preparation of low-temperature-stable alkanolic-aqueous solutions of polyethersulphonates of the general formula I R-(O-A)n-SO3M I in which R represents an alkyl or alkenyl group having 8 to 25 carbon atoms or an alkylphenyl group having 8 to 18 carbon atoms in the alkyl radical, A denotes a 1,2-alkylene group having 2 to 4 carbon atoms, n has a value of between 1 and 15 and M represents an alkali metal cation or an ammonium cation which can be substituted by C1-C4-alkyl groups or C1-C4-hydroxyalkyl groups, by reacting polyether halides of the general formula II R-(O-A)n-X II in which X represents chlorine or bromine, with an aqueous solution of an alkali metal sulphite or ammonium sulphite and diluting the reaction solution with a C4-C8-alkanol, by heating the reaction mixture after the reaction to 60 to 150 DEG C at 1 to 5 bar and separating the mainly aqueous phase which is formed in this process. The low-temperature-stable solutions of the polyethersulphonates I are used as surfactant solutions in tertiary oil drilling.

    Abstract: Enzymes or microorganisms are immobilised by mixing them with an aq. soln. contg. a water-soluble glycidyl ether (I) and a water-soluble amine (II) contg. at least 2 NH gps., opt. in partially neutralised form, and allowing the mixt. to gel. (I) is a prod. obtd. by reacting 1-30 equivs. of an epoxide of formula (III) with 1 equiv. of a 2-6C polyhydric alcohol or a mono- or disaccharide, reacting the prod. with epichlorohydrin, and opt. cyclising the prod. to form an epoxide. In (III), R1-R3 = H, Me or Et.

    Abstract: Enzymes are immobilized by mixing the following components with one another in aqueous solution: (a) an enzyme or a dispersed microorganism, (b) a water-soluble glycidyl ether, prepared by subjecting from 1 to 30 equivalents of an epoxide of the formula I (I) where R1, R2 and R3 are each hydrogen, methyl or ethyl, to an addition reaction with 1 equivalent (based on OH groups) of a polyfunctional alcohol of 2 to 6 carbon atoms or of a mono- or disaccharide to produce an adduct, reacting the adduct with epichlorohydrin and, if required, then carrying out cyclization to give the epoxide, and (c) a water-soluble amine possessing two or more NH groups, if necessary in a partially neutralized form, and allowing the mixture thus obtained to gel.

    Abstract: An improved process for dyeing or printing waterswellable cellulosic fibers and mixtures or said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of (a) polyethylene oxide, a block copolymer of ethylene oxide and propylene oxide or an ether, ester or carbamate derivative thereof and (b) a polyoxyethylated amine.
