The invention relates to a method for grinding an inorganic solid from the series cement clinker, pozzolan and/or raw material for cement production, where a grinding additive is added before or during grinding, and the grinding additive, based on the dry mass, comprises 6% to 80% by weight of caprolactam and 1.5% to 30% by weight of aminocaproic acid, where, based in each case on the dry mass, 0.002% to 2% by weight of the grinding additive is used, based on the total solid. Further claimed are a grinding additive and the use thereof for increasing the compressive strength of the cured product produced therewith.

Grinding additive for mineral binders

The invention relates to a process for preparing aminoalkanamides by reacting cyanoalkanoic esters with a) ammonia or an amine and b) hydrogen in the presence of a catalyst, the reaction with component b) being started simultaneously or not later than a maximum of 100 minutes after commencement of the reaction of the cyanoalkanoic ester with component a).

Method for the production of aminoalkane acid amides

Identification and quantification of mass-produced goods in articles, a dye-containing polymer dispersion having been added to the mass-produced goods. The polymer dispersions contain particles which are coded by a mixture of dyes, and the polymer dispersion particles are quantitatively determined.

Method for qualitatively and quantitatively identifying bulk goods

The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter&#x3c;500 nm. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.

Method for producing aqueous polymer dispersions containing colorants

A process for wrinkleproofing cellulosic textiles comprises treating the textiles with a finish and drying the treated textiles, wherein the finish comprises one or more water-soluble or water-dispersible hydrophobically modified polyethyleneimines and/or polyvinylamines. Suitable hydrophobically modified polyethyleneimines are hydrophobically modified homopolymers of ethyleneimine, hydrophobically modified graft polymers of polyamidoamines or of polyvinylamines. Suitable hydrophobically modified polyvinylamines are hydrophobically modified at least partially hydrolyzed homo- or copolymers of N-vinylcarboxamides. The polyethyleneimines and polyvinylamines can be crosslinked by polyfunctional crosslinking compounds, quaternized and/or modified by reaction with alkylene oxides, dialkyl carbonates, alkylene carbonates and/or C&#x2013;C-carboxylic acids. Suitable hydrophobicizing reagents are selected from the group consisting of long-chain linear or branched linear carboxylic acids, linear or branched alkyl halides, alkyl epoxides, alkylketene dimers, cyclic dicarboxylic anhydrides, alkyl isocyanates and chloroformic esters of fatty alcohols.

Hydrophobically modified polyethylenimines and polyvinylamines for wrinkle-resistant finishing of textiles containing cellulose

Alkylketene dimers are prepared by reacting acyl chlorides with tertiary amines in a molar ratio of from 1:1 to 1:1.6 at from 65 to 150&#xb0; C. and with a residence time of from 1 to 30 minutes in the absence of solvents with thorough mixing and isolation of the alkylketene dimers.

Method for producing alkylketen dimers

The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter <500 nm. The present invention also relates to perylene dyes of the formula III as set forth in claim 35. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.
