Title:
変性共役ジエン系重合体およびその製造方法ならびにその組成物
Document Type and Number:
Japanese Patent JP3769294
Kind Code:
B2
Abstract:
A modified polymer prepared by terminally modifying a conjugated diene polymer obtained by polymerization using a lanthanoid-containing catalyst in an organic solvent, with an N-substituted amino active compound, and having Mw of 100,000 - 1,000,000, a monomodal Mw distribution, Mw/Mn of 1.3 - 5, and a terminal modification of at least 50%. The modified polymer is produced by (1) polymerizing a conjugated diene by using a catalyst which is either a mixture of (i) a reaction product of a lanthanoid-containing compound with an organoaluminum hydride and then with a Lewis base, and (ii) a halo-compound, or is a reaction product of (i) with (ii) prepared by reacting a portion of conjugated diene monomer prior to reaction of (ii); and then (2) terminally modifying the obtained living polymer with an N-substituted amino active compound.
