Conjugated diene polymer end-modified with alkoxysilane derivative

摘要

The present invention relates to a conjugated diene polymer end-modified with an alkoxysilane derivative. More particularly, the present invention relates to an end-modified conjugated diene polymer, wherein an alkoxysilane derivative having an ether group and a dialkylamino group is bonded as end modifier to an end of a conjugated diene polymer, which is useful as a rubber material for a tire tread owing to improved compatibility with an inorganic reinforcing agent and improves dynamic mechanical properties such as wet traction, rolling resistance, Mooney viscosity, processability, etc.

主权项

1. An end-modified conjugated diene polymer, wherein the end-modified conjugated diene polymer is obtained by a reaction of an alkoxysilane-based end modifier an end of a conjugated diene polymer, where the alkoxysilane-based end modifier is represented by Chemical Formula 1: wherein R1 and R2, which are identical or different, represent C1-C10 alkyl, or tri(C1-C10 alkyl)silyl; R3 and R4, which are identical or different, represent C1-C10 alkyl; R5 represents C1-C10 alkyl or C1-C10 alkoxy; and n and m respectively represent an integer from 0 to 5.
