Abstract
The present invention provides an azasilane-based modifier of Formula 1, which may easily introduce a functional group having affinity with a filler into a conjugated diene-based polymer chain, a modified and conjugated diene-based polymer including the functional group derived from the azasilane-based modifier, a method for preparing the modified and conjugated diene-based polymer, a rubber composition including the modified and conjugated diene-based polymer, and a molded article and a tire manufactured from the rubber composition.
Claims12
A modified and conjugated diene-based polymer comprising a functional group which is derived from an azasilane-based modifier represented by the following Formula 1:
- in Formula 1,
- R1 to R4 are each independently selected from the group consisting of a halogen group, an alkyl group of 1 to 6 carbon atoms and an alkoxy group of 1 to 6 carbon atoms, and
- R5 is a divalent hydrocarbon group of 1 to 10 carbon atoms.
