Title:
MODIFIED CONJUGATED DIENE POLYMER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/136963
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a modified conjugated diene polymer which exhibits excellent workability and rebound resilience, drastically improves wear resistance and crack-growth resistance, has excellent low-heat-emitting properties, and has little energy loss; a method for producing the same; and a rubber composition using the same. The present invention pertains to a modified conjugated diene polymer characterized by being obtained by: polymerizing a conjugated diene compound by using a catalyst obtained from (A) an yttrium compound having a bulky ligand represented by general formula (1), (B) an ionic compound comprising a non-coordinating anion and a cation, and (C) an organic metal compound of an element selected from group 2, group 12 and group 13 of the periodic table; and modifying the product thereof by using a carbonyl compound. The present invention also pertains to a method for producing the same, and a rubber composition using the same.
