Claim Text:
1. A method for providing a polymer that comprises terminal functionality and a sulfide linkage, said method comprising: a) providing a living polymer that comprises polyene mer, b) introducing to said living polymer an episulfide so as to provide a polymer with a terminal thiolate moiety, said episulfide being provided in no more than a stoichiometric amount, and c) introducing to said polymer with a terminal thiolate moiety an epoxide that comprises at least one heteroatom-containing functional group, said epoxide being provided in at least a stoichiometric amount, said epoxide reacting with said thiolate moiety so as to provide terminal functionality with a hydroxyl group at the β position relative to the S atom of said thiolate moiety, thereby providing said polymer with said terminal functionality and said sulfide linkage.
