    摘要： The invention relates to a process for preparing fine-particle free-flowing rubber powders, composed of carbon black fillers and a rubber, prepared by solution polymerization. The process operates on the basis of a two-phase system involving transfer of the organic rubber phase in a non-aggressive manner into the inorganic filler suspension, without addition of chemicals. A rubber/carbon black composite is formed. The process comprises measures to avoid clumping of product in the aqueous phase. After mechanical water removal and thermal drying, the product obtained flows freely and is a storage-stable powder or pellet and are markedly superior to the standard both in their processing and in their rubber-technology property profile.

    摘要： A precipitated silica with the following physicochemical properties: BET surface area35 m2/g to 350 m2/g BET/CTAB surface area ratio0.8 to 1.1 Pore volume, PV1.6 ml/g to 3.4 ml/g Silanol group density3 ml/(1.5 g) to 9.5 ml/(1.5 g) (V2 = NaOH consumption) Average aggregate size250 nm to 1500 nm CTAB surface area30 m2/g to 350 m2/g DBP value150 ml/100 g to 300 ml/100 g V2/V1 by Hg porosimetry0.19 to 0.46 DBP/CTAB1.2 to 3.5 is produced by reacting alkali silicate with mineral acids at temperatures of 60° C. to 95° C. while maintaining a pH of 7.5 to 10.5 and continuously stirring, continuing the reaction to a solids concentration in the precipitation suspension of 90 g/l to 120 g/l, adjusting the pH value to a value of less than or equal to 5, filtering out, washing, drying and optionally grinding or granulating the precipitated silica. The precipitated silica is used as a filler in vulcanizable rubber compounds and vulcanizates.

    摘要： Finely divided, pulverulent rubbers containing filler which contain further processing and vulcanization auxiliaries necessary for the production of vulcanizable rubber mixtures, which rubbers are pourable even after exposure to mechanical action, and to a process for the production thereof. The rubber powder is obtained within two precipitation steps. These rubber powders are used for the production of vulcanizable rubber mixtures. The fillers used, which comprise not only precipitated silicas but also carbon blacks known in the rubber industry, are optionally surface modified with organosilicon compounds.
