Disclosed is a rubber composition comprising, based on 100 parts by weight of an 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. In addition, a tire having a component comprising such a rubber composition is disclosed. Finally, a method for forming a sulfur-vulcanizable rubber composition for incorporation into a tire is disclosed, the method comprising: selecting a starting material comprising a polyol or a polyol derivative; condensing the starting material with a fatty acid to produce an esterified material; silylating the esterified material to produce a silylated material; and combining the silylated material with at least one elastomer in a rubber composition, wherein the elastomer is selected from the group consisting of styrene-butadiene, polybutadiene, natural rubber, polyisoprene, and mixtures thereof.
公开了一种橡胶组合物,基于100重量份的弹性体(phr),其包含:一种或多种选自苯乙烯‑丁二烯、聚丁二烯、天然橡胶、聚异戊二烯和它们的混合物的弹性体;以及衍生自多醇或多醇衍生物的甲硅烷基化材料。此外,公开了一种具有包括这种橡胶组合物的部件的轮胎。最后,公开了一种用于形成用于并入轮胎中的用硫‑可硫化橡胶组合物的方法,该方法包括:选择包括多醇或多醇衍生物的起始材料;将所述起始材料与脂肪酸缩合以生成酯化材料;对酯化材料进行硅烷化以生成甲硅烷基化材料;以及将所述甲硅烷基化材料与橡胶组合物中的至少一种弹性体组合,其中所述弹性体选自苯乙烯‑丁二烯、聚丁二烯、天然橡胶、聚异戊二烯和它们的混合物。
