1. A process for preparing a functionalized diene monomer-containing polymer comprising:
a. polymerizing at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer to produce polymer chains with a living end;
b. reacting the living end polymer chains from (a) with a first functionalizing compound selected from:
i.
wherein n is an integer of 0 to 16, or
ii.
wherein R1 is selected from H and hydrocarbyl of C1-C20, and R2 is selected from H and hydrocarbyl of C1-C20,
thereby producing an intermediary product including polymer chains end functionalized with the first functionalizing compound;
c. coupling the intermediary product from (b) with a second functionalizing compound selected from
wherein B is boron, each R6 is independently selected from H and hydrocarbyl of C1-C20, and each X is a halogen,
thereby forming a final product including functionalized diene monomer-containing polymers having a trans-bond content of no more than 60% and functionalized with both a first functionalizing group resulting from the first functionalizing compound and a second functionalizing group resulting from the second functionalizing compound.
