Title:
変性共役ジエン重合体、その製造方法及びそれを用いたゴム組成物
Document Type and Number:
Japanese Patent JP6394589
Kind Code:
B2
Abstract:
An object of the present invention is to provide a modified conjugated diene polymer that is excellent in processability and impact resilience, has markedly improved abrasion resistance and crack growth resistance, is excellent in low heat generation properties, and has low energy loss, a method for producing the same, and a rubber composition using the same. The invention of the present application provides a modified conjugated diene polymer obtained by polymerizing a conjugated diene compound using a catalyst including from (A) an yttrium compound having a bulky ligand represented by general formula (1), (B) an ionic compound formed of a non-coordinating anion and a cation, and (C) an organic metal compound of an element selected from the group consisting of group 2, group 12 and group 13 of the periodic table and modifying the conjugated diene polymer with a carbonyl compound, a method for producing the same, and a rubber composition using the same.
