Abstract

Silane-modified biopolymeric, biooligomeric, oxidic or siliceous filler obtainable by reacting at least one biopolymeric, biooligomeric, oxidic or siliceous filler in a compressed gas with at least one silane. The silane-modified biopolymeric, biooligomeric, oxidic or siliceous fillers are used in rubber compounds.
