Abstract: Detergents which contain from 0.01 to 20% by weight of oxyalkylated, carbonyl-containing polymers can be prepared by reacting. (A) a polymer which contains, as copolymerized units, one or more monoethylenically unsaturated C3-C6-carboxylic acids with (B) ethylene oxide, propylene oxide, n-butylene oxide, isobutylene oxide or a mixture of these, in an aqueous medium at up to 150 DEG C.

Abstract: Photopolymerizable recording materials which are suitable for the production of photoresist layers, and contain one or more thermoplastic vinyl polymers as the binder, one or more low molecular weight, ethylenically unsaturated, photopolymerizable compounds and one or more photoinitiators, with or without other, conventional additives and/or assistants, have excellent adhesion to metallic substrate surfaces if the binder employed is a vinyl polymer which possesses amino and/or imino groups.

Abstract: The invention relates to a process for the removal of the catalyst in the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols by oxidative coupling reaction with oxygen at temperatures between 15 and 50 DEG C in the presence of a catalyst complex comprising a metal salt and an organic amine in the presence of a solvent, and removal of the metal ion component of the catalyst from the polyphenylene ether solution by means of complexing or chelate complexing compounds in aqueous medium, the complexing and removal of the metal ion component of the catalyst being carried out in the presence of from 0.1 to 5000 mg/kg of high-molecular-weight, at least partially water-soluble polymers of (meth)acrylic acid and/or of (meth)acrylamide.

Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I I where R1, R2, R3 and R4 are each hydrogen or a non-ionic substituent, X and Y are each the radical of a methylene-active compound, or of an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine or hydrazine, and Z is hydrogen, methyl or phenyl, and the production of this recording medium.

Abstract: A process for the preparation of acetylene copolymers by catalytic polymerization of a mixture of acetylene and dialkynes or polyalkynes, using Ziegler catalysts. The novel polymers may be used as colored pigments, as colored coatings for metal, glass or plastics, and for the production of electrical or magnetic components.

Abstract: A process for the manufacture of nylons by heating an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH2RNH2, where R is alkylene of 6 to 12 carbon atoms or is a radical to a temperature at which a nylon is formed, under superatmospheric pressure and with removal of water. The solution used is an aqueous solution of from 75 to 90 percent strength by weight of a salt of a dicarboxylic acid and a diamine, which solution has been obtained by neutralizing a less concentrated salt solution, which contains an appropriate dissolved excess of the particular dicarboxylic acid, with the corresponding diamine. The nylons obtained are used for the manufacture of moldings.
