ABSTRACT:
There is provided herein a rubber composition comprising (a) at least one rubber component; (b) at least one silane-reactive filler; (c) optionally, at least one activating agent and, (d) at least one silane of the general Formula (1):in-line-formulae description="In-line Formulae" end="lead"?[X1X2X3Si—]d(G)a[—Y—(CR3-e-Ze)b]c (1)in-line-formulae description="In-line Formulae" end="tail"?wherein X1is selected hydrolyzable groups; X2and X3are independently hydrocarbons or selected hydrolyzable groups;G is a hydrocarbon group of from 1 to 18 carbon atoms that can optionally contain at least one heteroatom selected from the group consisting of oxygen, sulfur, phosphous and silicon; each Y can independently be an unsaturated group; each Z can independently be a halogen atom; and, each R can independently be hydrogen, alkyl, alkenyl, aryl or aralkyl. There is also provided a process of preparing a rubber composition comprising mixing (a), (b), optionally (c), and (d). There are also provided articles (e.g., tires) made from the rubber composition.
