Abstract:
1. A functional polymer that is 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 1 is a bond or a divalent organic group, and α is a sulfur-containing heterocycle located at the terminal end of the polymer and selected from the group consisting of thiirane, thietane, thiolane, thiazoline, dihydrothiophene, thiadiazine, thioxanthene, thianthrene, phenoxathiin, dihydroisothiazole, and thienofuran groups or substituted forms thereof, where π may optionally include a functional group at the head of the polymer chain.
