Abstract
It has been discovered that the use of a silica dispersing aid, a polymerized (substituted) imidazolium liquid ionomer (PSI), in vulcanizable rubber compositions, provides an increase in the compound modulus and satisfactory processing of silica-containing rubber compounds, especially for tire components, without sacrificing other beneficial rubber properties or increasing hysteresis.
