abstract |
The present invention relates to a modifier and a modified and conjugated diene-based polymer including a functional group derived therefrom, and more particularly, provides a modifier including a compound represented by Formula 1, a modified and conjugated diene-based polymer including a functional group derived from the modifier and a repeating unit derived from a conjugated diene-based monomer, and methods for preparing them.n n In Formula 1, the definition of each substituent is the same as defined in the description of the invention. |
