Abstract: A storage-stable, moisture-cured, single-component polyurethane system comprising (a) a polyurethane prepolymer having an NCO content of from about 1 to 10 weight percent prepared by the reaction of higher molecular polyols and aromatic polyisocyanates, (b) at least one polyaldimine having the structural formula in which R is a multivalent linear or branched or cyclic hydrocarbon radical, which optionally is interrupted by alkylene-, sulfonyl-, thio- and/or oxy groups as bridge members, or is a multivalent polyoxyalkylene radical, (c) optionally an aromatic and/or aliphatic carboxylic acid or arylsulfonic acid, and (d) optionally auxiliaries and/or additives. The polyurethane systems are useful as sealing, casting, patching, cementing and coating compounds.

Abstract: The invention relates to novel phenothiazine derivatives, to a process for their preparation, and in particular to the use of phenothiazine derivatives, preferably liquid at 20 DEG C, of the formula in which R and R are identical or different and are hydrogen, halogen, an alkyl, alkoxy or alkylmercapto group having 1 to 18 carbon atoms, or an optionally substituted phenyl radical, R is hydrogen or a methyl, ethyl and/or methylol radical, n is an integer from 1 to 20, and m is an integer from 3 to 12, as stabilisers, preferably against UV radiation and thermal degradation, for plastics prepared by the polyisocyanate polyaddition process, preferably compact or cellular polyurethane polyurea elastomers.

Abstract: Diphenylmethane diisocyanate-based liquid polyisocyanate mixtures containing urethane groups and having an isocyanate content of from 12 to 30 percent by weight are obtained by reaction of a polyoxypropylene polyoxyethylene polyol containing 5 to 30 percent by weight of oxyethylene with diphenylmethane diisocyanate-based isocyanates. These polyisocyanate mixtures are storage stable at low temperature and yield flexible polyurethane foams having improved mechanical properties.
