Patent ID: 7671139

Claim:
A functionalized polymer defined by the formula where π is a polymer chain selected from the group consisting of polybutadiene, polyisoprene, poly(styrene-co-butadiene), poly(styrene-co-butadiene-co-isoprene), poly(isoprene-co-styrene), and poly(butadiene-co-isoprene), R 10 is a divalent organic group, and β is a hydroxyl group, an alkoxyl group, or an amine group, where the amine group is represented by the formula —NR 2 , where at least one R is a monovalent organic group and where the second R is hydrogen or a monovalent organic group, and where the alkoxyl group is represented by the formula —OR′, where R′ is a monovalent organic group.
