Surface-modified, oxidic or siliceous fillers and their use

摘要

The surface-modified fillers according to the invention are manufactured by treating oxidic or siliceous fillers with a silane of the formulaPPR.sup.1 R.sup.2 R.sup.3 Si--X.sup.1 --(--S.sub.x --Y--). sub.m --(--S.sub.x --X.sup.2 --SiR.sup.1 R.sup.2 R.sup.3).sub. nPPand are used for the manufacture of rubber vulcanizates, particularly tyres, with reduced dynamic damping and favourable abrasion behaviour.
