Abstract: Preparation of bis(silylalkyl)disulphanes of formula (R R R SiR )2S2 (I) comprises (1) reacting silylalkyl polysulphide(s) of formula (R R R SiR )2Sn (II) with a nucleophilic compound (III) of formula M CN (IIIA), M 2SO3 (IIIB) or R R R P (IIIC) in an amount equimolar to the number of sulphur atoms to be removed from (II); (2) filtering the resultant solid; and (3) purifying (I). In the formulae, R -R , R -R = 1-8C alkyl and/or alkoxy, H or monovalent aryl, preferably phenyl, toluyl or benzyl; R = divalent 1-8C, preferably 2-4C alkylidene or a group of formula (IV); n = 3-20, preferably 3-10; and M = an alkali cation, optionally substituted ammonium ion or half alkaline earth or zinc ion. Preferably a mixture of (IIIA), (IIIB) and (IIIC) is used. Reaction is carried out in the presence of a solvent for (III) at a temperature between 20 degrees C and the b.pt. of the solvent, especially in a 2-phase system in the presence of a phase transfer catalyst.

Abstract: Homogeneously waterproofed concrete is produced by adding an aqueous emulsion containing a hydrolysable alkoxysilane compound and optionally condensation products thereof to the fresh concrete mix containing water, inorganic and possibly organic components and then allowing the mix to harden. A process for the production of bulk-waterproofed concrete, in which a water-containing mixture of known inorganic components and possibly small amounts of organic components is treated during (or possibly after) its production with an aqueous emulsion containing an organo-silicon compound of formula (I) and optionally condensation products thereof, and then allowed to harden. R, R1 = optionally branched 1-3C alkyl; R3 = 1-20C (preferably 1-10C) alkyl or phenyl; a = 0 or 1; b = 1 or 2; c = 1-18; X = H, Cl, Br, I, NH2, SCN, CN, N3, NHR, N(R)2, N(R)3 or aryl (especially phenyl) if b = 1, or alkenyl (especially 1-6C alkenyl) if b = 2, or Sx (with x = 1-6) if b = 2 and c = 1-6, or any group if b = 2 and c = 1-12 (preferably 1-6) . An Independent claim is also included for concrete mixtures containing known inorganic and possibly organic components plus an aqueous emulsion as above.
