    Abstract: The prodn. of isocyanurate gp.-contg. polyisocyanates (A) comprises partial trimerisation of (cyclo)aliphatic di-isocyanates (B) in the presence of tetra-alkylammonium alkyl carbonates of formula (I) and/or quat. ammonio-alkyl carbonate betaines of formula (II) as catalyst(s), followed by deactivation of the catalyst on reaching the required deg. of trimerisation. In formulae, R , R , R = 1-20 C alkyl, 5-6C cycloalkyl, 7-10C aralkyl or Ph; or R + R can form a 5- or 6-membered cycloalkyl gp., or R + R + N can form a 5- or 6-membered ring with another N or O as bridging gp. or R + R + R + N can form a multi-membered ring with one or more extra N and/or O bridges; R = 1-4C alkyl; R = 2-20 C alkylene, 5-6C cycloalkylene, 7-10C aralkylene or phenylene; or R + R = alkylene gp. which forms a 5- to 7-membered ring with a N bridge. Pref. trimerisation catalysts are carbonates of formula (III), (IV), or (V), or betaine carbonates of formula (V), (VII) or (VIII). Trimerisation is carried out at 30-150 degrees C and the catalyst is deactivated with dibutyl phosphate (DBP); unreacted monomeric di-isocyanate is then removed. Pref. di-isocyanates are (cyclo)aliphatic di-isocyanates obtd. by a phosgene-free process, esp. by thermal cleavage of (cyclo)aliphatic dicarbamate esters; esp. pref. di-isocyanates obtd. by this method are 1,6-hexamethylenedi-isocyanate (HDI), 2-butyl-2-ethyl-pentamethylene-1,5-di-isocyanate and 1-isocyanato-3-isocyanatomethyl-3,5,5-trimethylcyclohexane (IPDI).

    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 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.
