摘要:
This invention relates to a rubber composition which contains a dispersion of a particulate hydrophilic water absorbing polymer and tire with a tread thereof.
摘要:
The invention relates to a tire having at least one component comprised of a rubber composition which contains a hydrophobated, pre-silanized silica, namely a pre-silanized silica hydrophobated with an epoxidized soybean oil and/or epoxidized rubber tree seed oil in situ within said rubber composition. Such tire component may be, for example although not limited to, a tire tread, sidewall and/or sidewall insert.

This invention relates to a precipitated silica reinforced conjugated diene-based elastomer composition containing an alkoxysilane coupled, in-chain functionalized, conjugated diene-based elastomer and to a tire having at least one component thereof. Said in-chain functionalized conjugated diene-based elastomer is a conjugated diene-based elastomer which contains a plurality of at least one of in-chain p- and m-(2-pyrrolidinoethyl) styrene (PES) and m-(2-pyrrolidino-1-methylethyl) alpha-methylstyrene (PAMS) groups.
摘要:
This invention relates to the preparation of a cis 1,4-polyisoprene rubber-rich rubber composition containing precipitated silica which has been pre-treated with a fatty alcohol and/or epoxidized soybean oil together with an organosilane containing polysulfide coupling agent and to tires having at least one component comprised of such rubber composition. The invention particularly relates to a process of (a) preparing a natural rubber-rich rubber composition comprised of pre-treating precipitated silica aggregates prior to blending with, or in the presence of, dry natural rubber with a fatty alcohol and/or epoxidized soybean oil to the exclusion of sulfur curative for the natural rubber, mixing an organalkoxysiloxane based polysulfide coupling agent with said dry natural rubber coincidentally with or subsequent to said precipitated silica aggregate fatty alcohol and/or epoxidized soybean oil pre-treatment to form a composite thereof, to the exclusion of sulfur curative, followed by (b) mixing the resulting rubber mixture with sulfur curative and (c) curing the resulting rubber composition.

The present invention is directed towards speckled tire treads for tires. Specifically, the speckled tire tread includes a primary tread compound that serves as a matrix in which is distributed discrete particles of one or more secondary tread compounds, at least one of the compounds is a different color than the other tread compound(s) so as to be visually distinguishable. For example, the primary tread compound may include carbon black pigment and be black in color while the secondary tread compound can include one or more pigments to provide the particles with non-black color. Thus, the colored particles have a visually distinguishable color from that of the primary tread composition. Additionally, at least a portion of the particles may be situated for viewing on a running surface of the tire tread so that a subject can visually distinguish between the compounds, and such observed compounds may provide a different tire performance characteristic(s).
