Abstract
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 R1 and R2 can be the same or different and represent hydrogen atoms or a moiety selected from the group consisting of wherein R3 groups can be the same or different and represent alkyl groups containing from 1 to about 10 carbon atoms, aryl groups, allyl groups, and alkyloxy groups of the structural formula —(CH2)y—O—(CH2)z—CH3, wherein Z represents a nitrogen containing heterocyclic compound, wherein R4 represents a member selected from the group consisting of alkyl groups containing from 1 to about 10 carbon atoms, aryl groups, and allyl groups, and wherein n, x, y and z represents integers from 1 to about 10, with the proziso that R1 and R2 can not both be hydrogen atoms.
