Abstract: In a process for preparing solutions containing at least one isocyanate, the above-defined solution is subjected to a treatment with hydrogen after the phosgenation and before the complete removal of the solvent and of residual phosgene. A process for preparing isocyanates or isocyanate mixtures is provided, and the isocyanates thus prepared can be used for preparing polyurethanes, in particular polyurethane foams.

Abstract: Mixtures which are curable by heating or irradiation with actinic light contain one or more cationically curable compounds, such as an epoxy, an olefinically unsaturated monomer, amino resin or phenolic resin, and as a cationically active curing catalyst one or more N-sulfonylamino-sulfonium salts of the formula such as N-p-toluenesulfonyl-N-methylaminodiphenylsulfonium hexafluorophosphate with or without quinones or peroxides are suitable, inter alia, for producing moldings, coatings, relief images and resist patterns.

Abstract: Disclosed is a method of preparing high molecular weight polyphenylene ethers from monohydric phenols. According to this method, the phenols are subjected to an oxydative coupling reaction with oxygen to produce poly(phenylene ethers) which are subsequently reacted with an epoxide of the general formula (I) (I) where R1 and R2 can be identical or different and are each alkyl, cycloalkyl, aryl, aryloxy, alkoxy or carboxyalkyl, each of which may contain a furtehr epoxide group, or C3-C20-alkyl-substituted amino, or R1 is hydrogen and R2 is one of the above groups, or R1 and R2 form part of a cycloalkyl ring. The polyphenylene ethers that are so obtained, are completely blocked and have a high molecular weight, a pale intresic colour and a high stability to thermal and thermooxidative attack.
