Abstract: A reactor for thermal cleavage of monofunctional and polyfunctional carbamic acid esters to the corresponding isocyanates and the hydroxyl components in the liquid phase, in which the geometry of the reactor, characterised by the degassing surface in proportion to the volume and the arrangement of the heating surfaces, makes possible the cleavage in a two-phase mixture which contains over 50% volumetric gas content.

Abstract: Silicon-containing polymers consist of a) from 65 to 99.95 parts by weight of one or more acrylates and/or methacrylates of an aliphatic alcohol of 1 to 12 carbon atoms (monomers A), b) from 0 to 30 parts by weight of one or more ethylenically unsaturated monomers capable of undergoing free radical copolymerization (monomers B), c) from 0.05 to 10 parts by weight of one or more anhydrides of an alpha , beta -monoethylenically unsaturated dicarboxylic acid of 4 to 10 carbon atoms (monomers C) or from 0.1 to 10 parts by weight of one or more monomers containing one or more isocyanate groups and capable of undergoing free radical copolymerization (monomers D) and d) effective amounts of one or more silanes of the general formula I NH2-R1-Si(R2)3-m(R3)m(I) where m is 0, 1 or 2, R1 is a hydrocarbon chain of not more than 10 carbon atoms which may be interrupted by oxygen or nitrogen, the radicals R2 are identical or different hydrolyzable groups and the radicals R3 are identical or different C1-C5-alkyl groups. These silicon-containing polymers are suitable as base polymers for the preparation of sealing compounds curable under the action of atmospheric humidity.

Abstract: The invention concerns a method of producing organic di- and/or polyurethanes by reacting organic di- and/or polyamines (a) with urea and/or carbamic acid alkyl esters (b) and alcohols (c) in the presence of soluble zirconium compounds, preferably zirconium alcoholates, zirconium acetate or zirconium actylacetonate, as a catalyst (d). The invention also concerns the use of such compounds in the production of di- and/or polyisocyanates by thermal decomposition.

Abstract: The invention relates to novel 2,2-dialkylpentane 1,5-diisocyanates, 2,2-dialkylpentane-1,5-diurethanes and 2,2-dialkylpentane-1,5-dicarbamoyl chlorides of the formula in which R , R denote identical or different linear C1- to C12-alkyl radicals, branched C3- to C12-alkyl radicals, branched C2- to C12-alkenyl radicals, branched C4- to C12-alkenyl radicals or the radicals R and R together denote an alkylene group having 4 to 7 C atoms which is unsubstituted or substituted by one to 5 C1- to C4-alkyl groups and X denotes an NCO-, NH-CO2R -, NHCO2R - or NHCOCl- group, in which R and R are identical or different and denote a linear C1- to C20-alkyl radical, a branched C3- to C20-alkyl radical or a C5- to C12-cycloalkyl radical. The 2,2-dialkylpentane-1,5-diurethanes are, for example, pest control agents and are suitable, as are the 2,2-dialkylpentane-1,5-dicarbamoyl chlorides, for example, for the preparation of 2,2-dialkylpentane 1,5-diisocyanates, which in turn are used for the preparation of compact or cellular plastics by the polyisocyanate polyaddition process.
