Abstract:

ABSTRACT Mercapto–silanes enable an improved silica dispersion state compared with sulfide–silanes in tire tread compounds, which causes a better balance of wet grip and rolling resistance. However, it also causes a higher Mooney viscosity and a shorter scorch time, which results in processing difficulties. The reason for this behavior is not clear. Because the already deeply investigated silica–silane reaction cannot explain the observed effects, the silane–polymer reaction was considered to be responsible and therefore has been evaluated in depth.
