ABSTRACT:
A method of terminating a living polymer comprising the step of reacting with a living polymer a terminator defined according to formula (I) ##STR1## where Z is a halogen atom; 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. Also provided are a vulcanizable composition of matter, a vulcanizate and a tire comprising the functionalized polymers of the present invention.
