Functionalized monomers and functionalized rubbery polymers made therewith

A functionalized rubbery polymer wherein said functionalized rubbery polymer is a polymer of at least one conjugated diene monomer or vinyl aromatic monomer, and a functionalized monomer having a structure according to the following formula:

• R1R2N—(CH2)n—X—CH2—CHR3R4
• wherein R1 and R2 are independently selected from a group consisting of alkyls, cycloalkyls, alkenyls, cycloalkenyls, aryls, phenyls, heterocycles, acyls, and silyls;
• or R1 in combination with R2 forms a heterocyclic ring.
• n is an integer from 1 to 20;
• X is selected from a group consisting of sulfur, a phosphorus moiety, and silicon moiety;
• R3 and R4 are selected from the group consisting of hydrogen, alkyls, alkenyls, and aryls;
• and at least one of R3 and R4 contain reactive unsaturation;
• and
• said functionalized monomer is present in about 0.1 percent by weight to about 10 percent by weight of said functionalized rubbery polymer.
