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.
