Abstract: OF THE DISCLSOURE The preparation according to the invention comprises resorcinol and at least one carbon black in homogeneous distribution. The preparation is preferably in the form of beads or granulates. The preferred granular form is attained when the resorcinol has an average particle size of 0.10 to 0.40 mm or is reduced to this average particle size during the production process. Furnace blacks having a specific particle surface area of approximately 40 to 120 square metres per gram, an average primary particle size of 20 to 45 nm and a dibutyl phthalate absorption of 45 to 130 millilitres per 100 grams are preferred as carbon blacks. The preparation according to the invention preferably has a weight ratio of carbon black to resorcin between 70 to 30 and 30 to 70. The upper limit of this weight ratio is 95 to 5. The process for producing the resorcin-filler preparation in which carbon black is put into a mixer capable of high-speed performance and provided with a heating device, and when required with a cooling device, as well as with a propeller-type or rough mixing tool, resorcinol is liquefied by heating, the liquid resorcinol is fed into the fast running, heated mixer in batches or continuously, the step for forming the preparation is thus initiated, continued and completed until beads are formed and the beads are cooled or allowed to cool in the running mixer until they are free from tackiness.

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.
