Functionalized elastomer and tire comprising such an elastomer

摘要

The invention relates to a functionalized elastomer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and a functional group bonded to the backbone chain, the functional group comprising an oligopeptide or modified oligopeptide. It also relates to a functionalized elastomer having the structure I
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ X�S-Z] n €ƒ€ƒ€ƒ€ƒ€ƒ(I)
where X is a polymer derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; S is sulfur; �S - Z] is an oligopeptide radical with pendant sulfur S or modified oligopeptide radical with pendant sulfur S, and n is the number of �S - Z] groups bonded to X. The functionalized elastomner may be used in a tire.
