    Abstract: Oligomeric organosilane polysulfanes are novel. An oligomeric organosilane polysulfane (I) contains structural units (A), (B) and/or (C) in any linear, branched or cyclic arrangement whereby at least (A) or (B) is present. Independent claims are included for: (i) a process for the production of (I) by reaction of a compound of formula (1), optionally in a solvent and/or in the presence of a catalyst at 0-150 degrees C with addition of water to cause self polymerization or under analogous reaction conditions by copolymerization with a compound of formula (2); (ii) a rubber mixture (II) containing organosilane polysulfane (I); (iii) a process for the production of the rubber mixture (II) by addition of (I) and a filler to rubber; and (iv) molded articles prepared from (II). Y-Sx-(CH2)nSiR R R (1) RR R R Si (2) Y = H, CN, -(CH2)nSiRR R ; n = 1-8; R-R = H, 1-4C alkyl, 1-4C alkoxy, halogen or OSiR R R ; x = 1-8; z = 2-6; o, p, qq = 1-40; o+p+q = 2-40.

    Abstract: The stable, aqueous dispersion has between 20 and 80 Gew.-per cent related to the total quantity of the dispersion, metal and/or metalloid oxide powder present in the form of aggregates of primary particles. The powder has at least two types of powder with the same sign of surface charge for a given pH value and a zeta potential causing an electrostatic repulsion between the particles greater than the van der Waals attraction of the powder. The stable, aqueous dispersion has between 20 and 80 Gew.-per cent related to the total quantity of the dispersion, metal and/or metalloid oxide powder present in the form of aggregates of primary particles in the dispersion, where the mean diameter of the aggregate is between 10 and 300 nm and the mean diameter of the primary particles is between 5 and 50 nm. The powder has at least two types of powder with the same sign of surface charge for a given pH value and a zeta potential causing an electrostatic repulsion between the particles greater than the van der Waals attraction of the powder. AN Independent claim is also included for the following: a brushing-on color and a recording medium.

    Abstract: Oligomeric organosilicon compounds consisting of ethylene-polysulfane chains in which each ethylene unit is substituted with one triorganosilylalkyl group. Oligomeric organosilicon compounds of formula (I): R -R = H, 1-4C alkyl, alkoxy, haloalkyl or haloalkoxy, phenyl, aryl or aralkyl; Z = 0-6C alkylidene which may be attached to either of the two carbon atoms, with the free valency taken up by hydrogen; x = 1-6; n = 1-150. Independent claims are also included for: (a) a process for the production of (I) by reacting compounds of formula (II) with compounds of formula MSH or M2Sy, or with M2S and sulfur,at 20-150 degrees C and normal pressure or at up to 6 bar, optionally in presence of solvent and/or catalysts; (b) oligomeric organosilicon compounds (I) obtained by this process; (c) rubber mixtures containing (I); (d) a process for the production of rubber mixtures using rubber, other filler(s) and compounds (I); and (e) molded products obtained from these rubber mixtures. X = halogen; M = a metal ion; y = 2-6 (statistical average) The full definitions are given in the DEFINITION (Full Definitions) Field.
