Abstract: The present application relates to new active compound combinations composed, on the one hand, of prior art compounds metaconazole, 5-[(4-chlorophenyl)methyl]-2,2-dimethyl-1-(1H-1,2,4-triazol-1-yl-methyl)cy clopentanol and imidacloprid, 1-[(6-chloro-3-pyridinyl)-methyl]-4,5-dihydro-N-nitro-1H-imidazole-2-amine , and, on the other hand, of other prior-art active compounds, the combinations being extremely suitable for the protection of wood products.

Abstract: The present invention relates to an agent or concentrate for protecting sawn timber against wood-discolouring fungi, containing a fungicide on phenol basis and a fungicide on organo-iodine basis, optionally fungicides and insecticides, dissolved in an organochemical solvent or solvent mixture or in a mixture of water and organochemical solvent or solvent mixture and at least one emulsifier.

Abstract: In an aqueous sizing agent for glass fibers, comprising a bonding agent, a film-former and, optionally, a lubricant, wetting agent and/or other conventional additive, the improvement which comprises including therein a masked polyisocyanate which is water-soluble or dispersible. The sized glass fibers are especially useful in reinforcing polymeric products such as polyamides, giving improved physical properties.

Abstract: The invention provides new sizing agents, in particular for paper, which contain chloroformic acid esters of ester alcohols and/or carboxamide alcohols.The chloroformic acid esters in question preferably have the following idealized structure:(RCOX).sub.n R'(OCOCL).sub.m (I)whereinX=an oxygen atom or an NH radical,R=an aliphatic, araliphatic or cycloaliphatic hydrocarbon radical having 8 to 28 carbon atoms,R'=the radical of an (n+m)-functional alcohol or amino alcohol having 2 to 10 carbon atoms, where the functionality refers to the total number of OH and NH.sub.2 groups,n=an integer from 1 to 4, andm=an integer from 1 to 3.

Abstract: Diisocyanates corresponding to the general formula ##STR1## wherein R denotes the residue of an aliphatic, cycloaliphatic or aromatic diisocyanate andR' denotes an alkyl group,and a process for the preparation of these diisocyanates by the reaction of a trialkylsilyl cyanide with at least 2 mol of an organic diisocyanate at -25.degree. C. to 200.degree. C.

Abstract: The present invention relates to a process for the production of compounds containing reversibly blocked and, optionally, free alcoholic hydroxyl groups, characterized in that organic compounds containing at least one alcoholic hydroxyl group, but otherwise being inert under the reaction conditions are reacted at 0.degree. to 140.degree. C. with N,N'-disubstituted 5-acylimino-imidazolidine diones. The present invention also relates to the use of these compounds for the production of polyurethanes.
