Title:

POLYMERIZATION INITIATOR COMPOSITION, PREPARATION METHOD THEREFOR, AND METHOD FOR PREPARING POLYMER USING SAME

Document Type and Number:

WIPO Patent Application WO/2018/128315

Kind Code:

A2

Abstract:

The present invention relates to a polymerization initiator composition, a preparation method therefor, and a method for preparing a polymer using the same. The polymerization initiator composition of the present invention can prevent instability, inactivity, and deteriorations in SSBR properties of a polymerization initiator, minimize byproducts and unreacted materials, and significantly improve conversion rates, by comprising isomers of the polymerization initiator. Furthermore, a polar additive is already added in the preparation of the polymerization initiator, and thus a polar additive does not need to be separately added in the polymerization of polymers and the hydrophobic SSBR and hydrophilic silica can be effectively dispersed.
