ABSTRACT:
Precipitated silicas useful, for example, as fillers in elastomer mixtures or vulcanizates have a particularly broad pore size distribution of the pores with a pore diameter smaller than that of the maximum of the derivative of the pore volume distribution function, and have simultaneously very low microporosity and high rubber activity.
