    Abstract: There are prepared nitrogen containing alkoxysilanes of the formula (RO)3-n(CH3)nSi(CH2)mNHCON3 in which R is an alkyl group having 1 to 3 carbon atoms, n is 0, 1 or 2 and m is 1, 2 or 3 by a process comprising dissolving in an inert solvent an isocyanate group containing silane of the formula (RO)3-n(CH3)nSi(CH2)mN=C=O in which R, n and m are as defined above and reacting the silane with a water free hydrogen nitride or with hydrogen halide and an alkali metal-alkaline earth metal-, or ammonium azide at a temperature between 0 DEG C. and the boiling point of the inert solvent. The compounds are useful in making phosphinimines.

    Abstract: The present invention provides in a formable and vulcanisable rubber mixture which contains at least one rubber which still contains double bonds and which can be crosslinked with sulphur and a vulcanisation accelerator to form an elastomer from 0.2 to 10 parts by weight of sulphur, from 0.2 to 10 parts by weight of at least one vulcanisation accelerator and from 1 to 10 parts by weight of at least one silane corresponding to the formula (I) in which each of the individual radicals R and R1 represents an alkyl group containing from 1 to 4 carbon atoms, a cycloalkyl group containing from 5 to 8 carbon atoms or the phenyl radical; n is 0, 1 or 2, Alk is a difunctional straight-chain or branched hydrocarbon radical containing from 1 to 10 carbon atoms, and x is a number of from 2.0 to 8.0, or its hydrolysate and, the improvement in which the silane, vulcanisation accelerator and sulphur, expressed as S8, are present in such a molar ratio that, at the vulcanisation temperature, the rubber mixture has a reversion R resulting from the crosslinking isotherm (DIN 53 529) of 0 (+ 5%), R being calculated in accordance with the following formula: (II) in which Dmax is the maximum Vulcameter torque, Dmin is the minimum Vulcameter torque, D(max + 60 mins.) is the Vulcameter torque as measured 60 minutes after appearance of the maximum torque. The mixture is useful in the preparation of motor vehicle tires.

    Abstract: The invention relates to a silane/filler preparation, consisting essentially of from 5 to 70% by weight of at least one silane corresponding to the following formula Xp-CmH2m+1-pSiRn1(OR)3-n, I in which X=a halogen atom, preferably chlorine or bromine, p=1 or 2, m=1 to 5, R1=a C1-C5 alkyl group, C5-C8-cycloalkyl group or a phenyl group, R=a C1-C5-alkyl group, a C5-C8-cycloalkyl group, a phenyl group, a benzyl group or a C1-C5-alkoxy-C1-C5-alkyl group, and n=0, 1 or 2, and-respectively balanced to 100%-from 95 to 30% by weight of at lesat one inorganic filler, preferably carbon black and silicate fillers as, e.g., silica. There is also disclosed a process for the production of the silane/filler preparation and its use in optionally cross-linkable polymeric moulding compositions or vulcanizable or cross-linkable rubber moulding compositions such as sulphur-vulcanizable moulding compositions based on natural rubber and/or synthetic rubber.
