Abstract: Surface modification of natural or synthetic oxidic or silicate fillers (I) comprises using one or more organosilicon cpds. of formula: (R'n(RO)3-nSi-(Alc)m-(Ar)p)q(B) (I). In (I), B = -SCN (when q = 1) or -Sx- (when q = 2); R and R' = 1-4C alkyl, phenyl in which every R and R' is identical or different, R = 1-4C-alkyl-1-4C-alkoxy gp.; n = 0, 1 or 2; alc = bivalent, linear or branched 1-6C hydrocarbon; m = 0 or 1; Ar = 6-12C arylene gp.; p = 0 or 1 (p+m does not equal 0); x = 2-8. The novelty is that: (a) at least one organosilicon cpd. is intensively mixed with the filler at temps. less than 60 deg.C in a concn. of up to 3.5 x 10 power (-6) mol. trialkoxysilyl gps. on a square meter of filler surface; (b) followed by hydrophobising the homogenised mixt. in a preheated mixer, tempered bed or another suitable heated reaction vessel at temps. larger than 60 deg.C.

Abstract: A method of granulating resorcinol/silica mixtures which comprises transporting a mixture of resorcinol and precipitated silica by conveyor worms to two pressing rollers whose shafts are attached vertically above one another and whose contact pressure can be varied, compacting said mixture between said rollers, breaking up the compacted mixture with a cake breaker to obtain a granulate with minimum grain size and separating the remaining dusty portion of said mixture. The mixtures can be added to vulcanizable rubber to provide improved adhesion to rubber reinforcements.
