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: Compsns. (I) comprise (A) ethylene-propylene- nonconjugated diene rubber (EPDM); (B) conventional crosslinking system; (C) at least one alkoxysilane cpd. of formulae (1) or (2); (D) silica and/or silicate with specific surface (BET adsorption, ISO 5794/1, annexe D) 5-100 sq.m/g. In the formulae, R is 1-4C alkyl or alkoxy; R1 is 1-4C alkyl or Ph; R2 is 1-6C divalent straight or branched chain hydrocarbon gp.; R3 is 6-12C arylene; R4 is 2-20C monovalent straight or branched chain unsatd. hydrocarbon gp.; m, p are 0 or 1 but are not both 0; n is 0-2; q is 1 or 2; B is -SCN or -SH when q is 1 and -Sx- (where x is 2-8) when q is 2. A claimed process comprises vulcanising (I) by heating at 100-270 deg.C for 1-150 mins., according to temp..

Abstract: The rubber mixtures of this invention contain a non-conjugated ethylene-propylene-diene rubber or a blend of a non-conjugated ethylene-propylene-diene rubber with a diene rubber, a specific alkoxy silane compound and an amorphous silicic acid having a specific surface area of between 5 and 100 m /g (BET adsorption). The vulcanisates according to the invention are prepared by vulcanisation of these rubber mixtures. The rubber mixtures of this invention have excellent dynamic properties and excellent mechanical properties, dynamic fatigue resistance and heat-aging resistance. They furthermore allow the preparation of vulcanisates having the same properties.
