Abstract
A functionalized polymer comprising a polymeric segment, having at least one cyclic amine end group, defined according to formula (I) ##STR1## where Z is an anionically-polymerized polymer; R.sub.1 is selected from the group consisting of organic groups containing from 1 to about 12 carbon atoms and a bridging bond; each R.sub.2 is independently selected from the group consisting of hydrogen, organic groups containing from 1 to about 12 carbon atoms, and a bridging bond; each R.sub.3 is independently selected from the group consisting of hydrogen and organic groups containing from 1 to about 12 carbon atoms; a is an integer from 4 to about 16; and b is an integer from 0 to about 12; and optionally including a bridge, formed by the selection of two of said bridging bonds, the bridge having 0 to about 6 carbon atoms between the bridging ring members; said polymer having been crosslinked. Also provided are vulcanizable compositions of matter, vulcanizates, and tires of the functionalized polymers.
