Patent number: 5317057Abstract: 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.Type: GrantFiled: December 30, 1992Date of Patent: May 31, 1994Assignee: Bridgestone CorporationInventors: James E.
