Title:
POLYMERIZATION INITIATOR, MODIFIED CONJUGATED DIENE-BASED POLYMER, AND PREPARATION METHODS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/115996
Kind Code:
A1
Abstract:
The present invention relates to a polymerization initiator represented by chemical formula 1, a modified conjugated diene-based polymer obtained by using the same, preparation methods therefor, a rubber composition containing the same, and a tire manufactured from the rubber composition. [Chemical formula 1] [Chemical formula 2] In chemical formula 1, Cy is a cyclic saturated hydrocarbon group having 5 to 8 carbon atoms, substituted or unsubstituted with an alkyl group having 1 to 4 carbon atoms; and A1 and A2 each are independently a functional group represented by chemical formula 2. In chemical formula 2, R is a linear hydrocarbon group having 1 to 20 carbon atoms or a monocyclic or multicyclic saturated hydrocarbon group having 3 to 20 carbon atoms; X is a divalent hydrocarbon group having 1 to 5 carbon atoms; M is an alkali metal; and a is 0 or 1.
