摘要： The present invention relates to a polymerization initiator composition, a preparation method thereof and a method for preparing a polymer using the same, and the polymerization initiator composition of the present invention can comprise isomers of the polymerization initiator, thereby preventing instability and inertness of the polymerization initiator and physical property degradation of the SSBR, minimizing by-products and unreacted materials, and remarkably improving a conversion ratio. In addition, the polymerization initiator composition according to the present invention does not need to add a polar additive separately upon polymer polymerization, since the polar additive is already added at the time of preparing the polymerization initiator, and there is an advantage of effectively dispersing the hydrophobic SSBR and the hydrophilic silica.
