Assignee: BRIDGESTONE CORPORATION
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 15:
16. A method for providing a functionalized macromolecule that comprises hydrogenated interpolymer and non-hydrogenated polymer portions, said method comprising:
a) providing a terminally functionalized interpolymer that comprises
1) vinyl aromatic mer,
2) conjugated diene mer,
3) hydrogenated products of conjugated diene mer, and
4) a terminal functionality which is reactive toward carbanions and comprises a functional group capable of interacting with silica;

b) introducing said interpolymer to, or introducing to said interpolymer, a carbanionic polymer that comprises conjugated diene mer, said carbanionic polymer optionally having a number average molecular weight of from 5 to 50 kg/mol; and
c) allowing said carbanionic polymer to react with said terminal functionality so as to provide said functionalized macromolecule.
