Treated Fillers, Compositions Containing Same, and Articles Prepared Therefrom

摘要

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 an unsaturated fatty acid, derivative of an unsaturated fatty acid, or salt 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.

1. A process for producing treated filler comprising:
(a) treating a slurry comprising untreated filler wherein said untreated filler has not been previously dried, with a treating composition comprising a treating agent, thereby forming a treated filler slurry; and (b) drying said treated filler slurry to produce treated filler, wherein said treating agent comprises at least one of:
an unsaturated fatty acid comprising a linear or branched, optionally substituted C4 to C38 alkyl having at least one carbon-carbon double bond;a derivative of said unsaturated fatty acid of (i), wherein at least one carbon-carbon double bond is reacted to include at least one functional group; and/ora salt of said unsaturated fatty acid of (i), wherein said unsaturated fatty acid (i), said unsaturated fatty acid of said derivative (ii), and said unsaturated fatty acid of said salt (iii) are in each case the same or different.
