Abstract

The present invention is directed to a stereoregular functionalized elastomer represented by poly(M1 co M2), wherein the functionalized elastomer comprises a microstructure selected from the group consisting of microstructures having at least 90 percent by weight of monomer residues in trans 1,4-configuration, and microstructures having at least 80 percent by weight of monomer residues in cis 1,4-configuration; wherein M1 is selected from the group consisting of isoprene and 1,3-butadiene; and M2 is of formula 4 wherein R6 is a covalent bond, phenylene, a linear or branched alkane diyl group containing 1 to 10 carbon atoms, or a combination of one or more phenylene groups and one or more linear or branched alkane diyl groups containing 1 to 10 carbon atoms; R7 is hydrogen or a linear or branched alkyl group containing 1 to 10 carbon atoms; X1 is selected from formulas 5 and 6 wherein R8 and R9 are independently trialkylsilyl, phenyl or a linear or branched alkyl group containing 1 to 10 carbon atoms, or one of R8 and R9 is hydrogen and the other is phenyl or a linear or branched alkyl group containing 1 to 10 carbon atoms, or R8 and R9 taken together with the nitrogen atom represe…
