TERMINAL MODIFIER OF FUNCTIONALIZED AMINOSILANE, METHOD FOR PREPARING MODIFIED CONJUGATED DIENE POLYMER USING THE SAME, AND MODIFIED CONJUGATED DIENE POLYMER PREPARED USING THE SAME

摘要

The present invention relates to a terminal modifier for a conjugated diene polymer, which improves mechanical properties, such as wear resistance, and processability of a conjugated polymer contained in a rubber composition. Particularly, the present invention relates to a terminal-modified conjugated polymer comprising an amino silane-based terminal modifier represented by chemical formula 1 bound to the end of a conjugated diene polymer, and a method for preparing the same. In chemical formula 1, each of R1 and R2 represents a C1-C20 hydrocarbon or a C1-C20 hydrocarbon containing a hetero atom; R3 is a C1-C10 hydrocarbon; each of R4 and R5 is a C1-C20 hydrocarbon; and n is an integer of 1-3.
