POLYMERIZATION CATALYST FOR CONJUGATED DIENE POLYMER, PROCESS FOR PRODUCING CONJUGATED DIENE POLYMER WITH THE SAME, RUBBER COMPOSITION FOR TIRE, AND RUBBER COMPOSITION FOR GOLF BALL |
摘要 |
[Subject] A catalyst for polymerization of conjugated diene is provided, which facilitates manufacture of a conjugated diene polymer with a high 1,4-cis structure content, leaves less aluminum residue on polymerization, and has high activity. A method of manufacturing conjugated diene polymers using the catalyst is also provided. [Solution] A catalyst for polymerization of conjugated diene comprises (A) an yttrium compound; (B) an ionic compound including a non-coordinate anion and a cation; and (C) an organometallic compound including an element selected from the groups 2, 12 and 13 of the periodic table. |
