Abstract: A process for the manufacture of a highly concentrated aqueous solution of a salt of a dicarboxylic acid and a diamine, as well as of a nylon precondensate, by reacting 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 An aqueous solution, of lower concentration, of a salt of a dicarboxylic acid and a diamine, containing an appropriate dissolved excess of the particular dicarboxylic acid, is reacted with the particular diamine in the molten state, in an equivalent amount to the dissolved dicarboxylic acid, the reaction being carried out under superatmospheric pressure and the final reaction temperature being kept at from 140 DEG to 210 DEG C. The solution obtained is used for the manufacture of a nylon.

Abstract: The invention relates to polyethylene terephthalate moulding compositions which are stabilised against degradation of the molecular weight during the processing in the melt. They contain a stabilising mixture of a) a tetracarboxylic dianhydride, preferably pyromellitic dianhydride, b) an aryl carboxylate, preferably diphenyl carboxylate, and c) a diglycidyl ether, preferably of bisphenol-A. The moulding compositions can be used to produce injection mouldings.

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: 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 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.
