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 the 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 R^1 and R^2 represents a C1-C20 hydrocarbon or a C1-C20 hydrocarbon containing a hetero atom; R^3 is a C1-C10 hydrocarbon; each of R^4 and R^5 is a C1-C20 hydrocarbon; R^6 is a C1-C10 hydrocarbon when m is 1; n is an integer of 1-3; and m is an integer of 1-2.
