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) 0.1 weight percent to 2 weight percent of at least one monomer having the structural formula:wherein R represents an alkyl group containing from 1 to about 10 carbon atoms or a hydrogen atom, wherein R′ represents a methyl group or a hydrogen atom, with the proviso that if R represents an alkyl group then R′ represents a hydrogen atom, wherein R1and R2can be the same or different, wherein R1represents an alkyl group that is functionalized with a leaving group, wherein R2represents a moiety selected from the group consisting of hydrogen atoms, alkyl groups containing from 1 to 18 carbon atoms, aryl groups containing from 6 to 18 carbon atoms, alkaryl groups containing from 7 to 18 carbon atoms, and alkyl groups that are functionalized with a leaving group, wherein the rubbery polymer is void of moieties containing tertiary amine groups, and wherein the rubbery polymer is void of repeat units which are derived from α,β-olefinically unsaturated amides.
