This invention discloses a functional monomer, its use in a polymer, a rubbery composition, a tire, and a process to make such a rubbery composition. The functional monomer has a structural formula selected from the group consisting of:
wherein the R 1 groups can be the same or different and represent hydrogen atoms or alkyl groups containing from 1 to 8 carbon atoms, wherein R 2 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, wherein R 3 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, wherein R 4 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, with the proviso that if R 3 represents an alkyl group then R 4 represents a hydrogen atom, and with the proviso that R 4 represents an alkyl group then R 3 represents a hydrogen atom, and wherein the R 5 groups can be the same or different and represent alkyl groups containing from 1 to 8 carbon atoms. |
