    摘要： A mercaptofunctional silane is provided of general Formula (1): [HSG1SiZθZβ]m[HSG2SiZβ3]n[HSG3SiZβ2X]o[[HSG4SiZβX2]p   (1) wherein: each occurrence of G1, G2, G3, and G4 is independently a hydrocarbylene group containing from 1 to 30 carbon derived by substitution of a hydrogen on alkyl, alkenyl, aryl, or aralkyl or a divalent heterocarbon group containing 2 to 30 carbon atoms and one or more etheric oxygen (—O—) and/or sulfur (—S—) atoms; each occurrence of X is independently selected from the group consisting of —Cl, —Br, RO—, RC(—O)O—, R2C═NO—, R2NO—, —R, (HO)d-1G5O—, wherein each R is independently selected from the group consisting of hydrogen, straight, cyclic or branched alkyl that can or can not contain unsaturation, alkenyl groups, aryl groups, and aralkyl groups, wherein each R, other than hydrogen, contains from 1 to 18 carbon atoms, G5 is independently a substituted hydrocarbon group from 2 to 15 carbon atoms or a substituted heterocarbon group from about 4 to 15 carbon atoms and contains one or more etheric oxygen atoms; each occurrence of Zβ, which forms a bridging structure between two silicon atoms, is [—OG5(OH)d-2O—]0.5, wherein each occurrence of G5 is independently selected form the group consisting of a hydrocarbylene group of from 2 to 15 carbon atoms or a divalent heterocarbon group of from 4 to 15 carbon atoms containing one or more etheric oxygen atoms; each occurrence of Zθ, which forms a cyclic structure with a silicon atom, is independently given by —OG5(OH)d-2O—, wherein G5 is independently selected form the group consisting of a hydrocarbylene group of from 2 to 15 carbon atoms or a divalent heterocarbon group of from 4 to 15 carbon atoms containing one or more etheric oxygen atoms; and, each occurrence of subscripts d, m, n, o and p independently is an integer wherein d is from 2 to 6 in a first embodiment, 2 or 3 in a second embodiment and 2 in a third embodiment; m is 0 to 20; n is 0 to 18; o is 0 to 20; and, p is 0 to 20; with the proviso that m+n+o+p is equal to or greater than 2.

    摘要： Described are diol-derived organofunctional silanes in which the silanes contain cyclic and bridged alkoxy groups derived from hydrocarbon-based diols and methods for the preparation of the silanes. Also described are rubber compositions containing the diol-derived organofunctional silanes, methods for the preparation of the rubber compositions and articles of manufacture containing the rubber compositions, in particular, automotive tires and components thereof.
