3 Alkoxysillane modifying agent comprising tertiary amino group and preparation method of modified conjugated diene polymer using the same

摘要

In the present invention, the alkoxysilane-based modifier of formula (1) comprising at least three tertiary amino groups, which can easily introduce a filler affinity functional group into the conjugated diene-based polymer chain, a modification comprising a functional group derived from the alkoxysilane-based modifier Provided are a conjugated diene-based polymer, a method for producing the modified conjugated diene-based polymer, a rubber composition comprising the modified conjugated diene-based polymer, and molded articles and tires prepared from the rubber composition: [Formula 1] In Formula 1, R ¹ to R ⁷ , and p are as defined in the specification.
