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.
本发明涉及一种聚合引发剂组合物、其制备方法和使用该组合物制备聚合物的方法,本发明的聚合引发剂组合物可以包含聚合引发剂的异构体,从而防止聚合引发剂的不稳定性和惰性以及 SSBR 的物理性能退化,最大限度地减少副产物和未反应物质,并显著提高转化率。此外,根据本发明的聚合引发剂组合物无需在聚合物聚合时单独添加极性添加剂,因为在制备聚合引发剂时已经添加了极性添加剂,而且还具有有效分散疏水性 SSBR 和亲水性二氧化硅的优点。
