New organo-modified silicas for the reinforcement of SBR compounds

In the present work new organosilanes chemically bonded to different liquid polybutadienes are tested in order to replace TESPT and obtain modified silicas with a reduced hydrophilic character, which can, at least in principle, improve filler-matrix interactions and, consequently, tyre performances. Moreover, these new organosilanes could be usefully employed in compounds obtained by vulcanization processes which exploit peroxides or radiations instead of sulphur.
