Abstract: A novel organosilicon compound is claimed. The novel organosilicon compound is of formula R )(R )Si-R -S-Zn-S-R -Si(R )(R )(R (I). R - R = H, halogen or optionally branched alkyl or alkoxyl; and R = optionally branched alkylidene. Independent claims are also included for: (a) the preparation of (I) by reaction of a mercaptan compound of formula R )(R )Si-R -S-H (II) and a zinc alcoholate; (b) rubber mixtures containing compound (s) (I), rubber, filler and optional rubber additives; (c) preparation of the rubber mixtures by reaction of the components given in (b); and (d) mould forms comprising the rubber mixtures.

Abstract: In the production of anhydrous sodium sulfide, sodium sulfide containing 35-45% water with mixing is passed through an apparatus, in which the product temperature of approximately 20 degrees C at the place of solid injection gradually rises to at least 180 degrees C while the subpressure is maintained at less than 20, preferably less than 11 torr.

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.
