Beschreibung
Zusammenfassung:	La presente incluye un procedimiento para producir sílice precipitada tratada que incluye (a) combinar un silicato de metal alcalino y un ácido para formar una suspensión no tratada que comprende sílice no tratada, en donde dicha sílice no tratada no ha sido secada previamente; (b) secar la suspensión no tratada para producir sílice precipitada secada; (c) formar una suspensión acuosa de la sílice precipitada secada con una composición de tratamiento que comprende un agente de tratamiento, y opcionalmente un agente acoplante y/o, opcionalmente, un agente no acoplante para formar una suspensión de sílice precipitada tratada; y (d) secar la suspensión de sílice precipitada tratada para producir una sílice precipitada tratada secada. El agente de tratamiento puede incluir un ácido graso insaturado, un derivado de un ácido graso insaturado. The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler, where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include a polymer having (i) at least one first group that interacts with the untreated filler and (ii) at least one second group that interacts with a rubber matrix into which the treated filler is incorporated. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.
