摘要：
A functionalized polymer according to the invention includes a polymer molecule having the general formula AYLi where A is a cyclic amine-containing radical having the general formula ##STR1## wherein R.sub.1 is a divalent alkylene, an oxy- or amino-alkylene, or substituted alkylene having from 6 to about 20 carbon atoms; R.sub.2 is a linear-, branched-, or cyclo-alkylene having from about 2 to about 20 carbon atoms; and Y is a divalent polymer radical and Li is a lithium atom bonded to a carbon atom of Y.
