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.
本发明涉及一种以烯丙基二烯类聚合物为基础,末端修饰有烷氧基硅烷衍生物的共轭二烯聚合物。更具体地说,本发明涉及一种末端修饰的共轭二烯聚合物,其中末端修饰剂为具有醚基和二烷基氨基基团的烷氧基硅烷衍生物,该共轭二烯聚合物由于与无机增强剂的相容性提高以及动态力学性能(如湿地牵引力、滚动阻力、Mooney粘度、加工性等)的改善,适用于轮胎胎面的橡胶材料。
