摘要

Summary "process for producing treated filler, treated filler, rubber composition, process for producing treated precipitated silica and treated precipitated silica" The present invention includes a process for producing treated filler which includes (a) treating a paste that includes untreated filler, where the untreated filler has not been previously dried, with a treatment composition comprising a treating agent, thereby forming a treated filler paste; and (b) drying the treated filler to produce the treated filler. the treating agent may include a polymer having (i) at least one first group interacting with the untreated filler and (ii) at least one second group interacting with a rubber matrix to which the treated filler is incorporated. The present invention is also directed to the treated filler prepared by the process, as well as rubber and tire formulation compositions including the treated filler.
