First claim
Opening claim text (preview).
The invention claimed is: 1. A conjugated diene-based polymer comprising a functional group derived from a functionalizing agent which comprises one selected from the group consisting of the following Formulae 2a, 2b, 2d to 2l, or a mixture of at least two thereof: in Formulae 2a, 2b, 2d to 2l, TMS means trimethylsilyl, TES means triethylsilyl, and Me means methyl. 2. The conjugated diene-based polymer of claim 1 , wherein the conjugated diene-based polymer has a mooney viscosity of 10 MU to 90 MU at 100° C. and a polydispersity of 3.4 or less. 3. A rubber composition comprising the conjugated diene-based polymer according to claim 1 . 4. A tire part comprising the rubber composition according to claim 3 .
