Abstract
A rubber composition is disclosed comprising, based on 100 parts by weight of elastomer (phr): one or more elastomers selected from the group consisting of styrene-butadiene, polybutadiene, natural rubber, polyisoprene, and mixtures thereof; and a silylated material derived from a polyol or a polyol derivative. Also, a tire having a component comprising such a rubber composition is disclosed. Finally, a method of forming a sulfur-curable rubber composition for incorporation in a tire is disclosed, the method comprising: selecting a starting material comprising a polyol or a derivative of a polyol; condensing the starting material with a fatty acid to generate an esterified material; performing a silylation on the esterified material to generate a silylated material; and combining the silylated material with at least one elastomer in a rubber composition, the elastomer being selected from the group consisting of styrene-butadiene, polybutadiene, natural rubber, polyisoprene, and mixtures thereof.
