A composition includes an elastomer and a ketoximo silane or a ketoxime additive. The ketoximo silane corresponds to Formula I:;D-SA—B (I)where B defined as:;where D is selected from a C1 to C60 hydrocarbyl group, or when A is 0 or 1 a hydrogen, or the structure in Formula III;;;and wherein n and j are independently 1, 2, or 3, m and q are independently 0 or 1, z and t are independently 0 or 1 and (n+m+z) is equal to 3 and (j+q+t) is equal to 3; A is 0 or greater than or equal to 1; R1 and R2 are independently C1 to C60 divalent organic groups and may optionally include O, N S, Si, and/or P heteroatoms with the proviso that when A is 0 either of R1 and R2 may be a chemical bond; R3, R4, R8 and R9 are independently a hydrogen, or a C1 to C60 hydrocarbyl or alkoxy group optionally including O, N, S, Si and/or P; R5 and R6 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring; R10 and R11 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring. |

1. A composition comprising:
an elastomer selected from the group consisting of: styrene/butadiene copolymer, polyisoprene, polybutadiene, butadiene/isoprene copolymer, butadiene/isoprene/styrene terpolymers, isoprene/styrene copolymer, natural rubber, butyl rubber, ethylene-propylene-diene rubber and combinations thereof; a ketoximo silane corresponding to Formula I or VIII:
D-SA—B (I) wherein A is 0 or greater than or equal to 1;
wherein B is defined as: wherein D is selected from the group consisting of: the structure in Formula III, a C1 to C60 hydrocarbyl group, and hydrogen; where n and j are independently 1, 2, or 3, m and q are independently 0 or 1, z and t are independently 0 or 1 and (n+m+z) is equal to 3 and (j+q+t) is equal to 3; A is 0 or greater than or equal to 1; R1 and R2 are independently C1 to C60 divalent organic groups and may optionally include O, N S, Si, and/or P heteroatoms with the proviso that when A is 0 either of R1 and R2 may be a chemical bond; R3, R4, R8 and R9 are independently a hydrogen, or a C1 to C60 hydrocarbyl or alkoxy group optionally including O, N, S, Si and/or P; R5 and R6 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring; R10 and R11 are independently hydrogen or C1 to C60 hydrocarbyl groups and may optionally include O, N S, Si, and/or P heteroatoms, and may optionally be bonded together to form a cyclic ring; where n is 1, 2, or 3, m is 0 or 1, z is 0 or 1 and (n+m+z) is equal to 3; j is greater than or equal to 1; A is greater than or equal to 1; R1 is a divalent organic group and may optionally include O, N, S, Si, and/or P heteroatoms; R5 and R6 are independently H or C1 to C60 hydrocarbyl group, optionally including O, N, S, Si, and/or P heteroatoms, and may optionally together form a cyclic ring; R7 is H, C1 to C60 saturated or unsaturated alkyl groups and may and optionally include O, N, S, Si, and/or P heteroatoms, with the proviso R7 is H only when A is equal to 1; providing that if A is 0, then (1) D is the structure of Formula III, or (2) R1 is a chemical bond and D is hydrogen; and an inorganic filler. |
