Beschreibung
Zusammenfassung:	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 at least one of an anhydride, a cyclic imide, and a derivative thereof. 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. Cette invention concerne un procédé de production d'une charge traitée comprenant (a) le traitement d'une suspension épaisse qui contient la charge non traitée, la charge non traitée n'ayant pas été préalablement séchée, avec une composition de traitement qui contient un agent de traitement, pour former ainsi une suspension épaisse de charge traitée, et (b) le séchage de la suspension épaisse de charge traitée pour obtenir la charge traitée. L'agent de traitement peut comprendre au moins un anhydride et/ou un imide cyclique et/ou un de leurs dérivés. La présente invention concerne en outre une charge traitée préparée par le procédé, ainsi que des compositions de formulation de caoutchouc et des pneus contenant la charge traitée.
