Functionalized elastomers

摘要

This invention discloses a rubbery polymer which is comprised of repeat units that are derived from (1) at least one conjugated diolefin monomer, and (2) at least one functionalized monomer having of the structural formula:wherein R represents an alkyl group containing from 1 to about 10 carbon atoms or a hydrogen atom, and wherein R<1 >and R<2 >can be the same or different and represent hydrogen atoms or a moiety of the structural formula:wherein the R<3 >groups in repeat units and in different repeat units can be the same or different and represent hydrogen atoms or alkyl groups containing from 1 to about 4 carbon atoms, wherein n and x represents integers from 1 to about 10, with the proviso that R<1 >and R<2 >can not both be hydrogen atoms.
