ABSTRACT:
A (halomethyl arene)-modified elastomer is made by reacting a lithium terminated elastomer intermediate with the halogen atoms of a halomethyl vinyl arene compound. A road-contacting tread component for a pneumatic tire is fabricated from vulcanized elastomer made by vulcanizing an elastomer composition of a (halomethyl arene)-modified elastomer, a carbon black reinforcing agent, and a sulfur-based vulcanizing system. A process for making a (halomethyl arene)-modified elastomer includes polymerizing at least one diene monomer with a lithium-containing initiator, capping the lithium terminated elastomer by reaction with a halomethyl arene compound, and recovering the modified elastomer.
