ABSTRACT:
A vulcanizable elastomeric compound and products such as pneumatic tires and the like, are formed from a functionalized polymer having a functional group derived from an anionic polymerization initiator. The anionic polymerization initiator comprises the general formula ##STR1## where R.sup.1 -R.sup.5 are the same or different and are selected from the group consisting of hydrogen; alkyls having from alkyls having from 1 to about 12 carbon atoms; aralkyls having from 7 to about 20 carbon atoms; dialkylaminos having from 2 to about 20 carbon atoms; and, dialkylaminoalkyls having from 3 to about 20 carbon atoms. At least one of R.sup.1 -R.sup.5 is selected from the group consisting of the dialkylaminos and the dialkylaminoalkyls. Methods of the present invention include preparing functionalized polymers and reducing the hysteresis of vulcanizable elastomeric compounds.
