| 摘要 |
A copolymer comprising: a polymeric backbone chain derived from a monomer comprising (i) at least one conjugated diene monomer or (ii) at least one a diene based elastomer selected from the group consisting of solution polymerized styrene butadiene rubber, emulsion polymerized styrene butadiene rubber, natural polyisoprene rubber, synthetic polyisoprene rubber, and polybutadiene, and, optionally, (iii) at least one vinyl aromatic monomer; and a polymeric side-chain bonded exclusively to a terminal end of the backbone chain is disclosed. The side-chain comprises a polymer derived from a monomer having a hydrogen bond donor site and a hydrogen bond acceptor site or derived from an N-substituted monoalkylacrylamide. Also, a method of making a functionalized elastomer is disclosed. |
