Abstract

Silane compositions of the general formula are provided herein comprising[(RO)x(R1)(3-x)—Si-Mt]q-L-[(Ra)cAr—(CR2═CR22)y]z wherein R and R1 are independently a hydrocarbon group of from 1 to about 20 carbon atoms; R2 are each independently hydrogen or a hydrocarbon group of from 1 to about 20 carbon atoms; M optionally is a divalent hydrocarbon connecting group of from 1 to about 20 carbon atoms to link the silicon atom and the L group; L is a covalently bound hydrocarbon linking group of from 1 to about 20 carbon atoms or a heteroatom linking group selected from the group consisting of —O—, —S—, —NR3— wherein R3 is hydrogen or a hydrocarbon group of from 1 to about 20 carbon atoms; Ra is an alkyl group of 1 to 12 carbon atoms; Ar is a substituted or unsubstituted aromatic group; q is an integer of 1 to 4; t and c are each independently 0 or 1; and x, y and z are each independently integers of 1 to 3, inclusive, with the proviso that t is 1 when L is a heteroatom group. Also provided are processes for preparing the silane compositions and rubber composition comprising the silane compositions.
