A modified conjugated diene polymer is produced by a production method including a step of reacting a conjugated diene polymer having an active terminal with a compound [M]. The conjugated diene polymer having an active terminal is a polymer obtained by polymerizing a monomer containing a conjugated diene compound in the presence of a polymerization initiator containing at least one of an alkali metal compound and an alkaline earth metal compound, and compound [M] is a compound having a functional group F1, a functional group F2, and a functional group F3 and not having active hydrogen. In the formula, F1 is a functional group such as * 1-C (= E)-O-(* 1 represents a bonding bond with a carbon atom or a three-level carbon atom of a carbon-carbon unsaturated bond in a chain structure or a cyclic structure), F2 is a functional group such as-C (R7) = N-, and F3 is a functional group such as-Si (R8) 2 (OR9).
通过包括使具有活性末端的共轭二烯系聚合物与化合物[M]反应的工序的制造方法,制造改性共轭二烯系聚合物。具有活性末端的共轭二烯系聚合物为在包含碱金属化合物及碱土金属化合物中的至少一种的聚合引发剂的存在下,使包含共轭二烯化合物的单体聚合而获得的聚合物,化合物[M]为具有官能基F1、官能基F2及官能基F3且不具有活性氢的化合物。F1为基“*1‑C(=E)‑O‑”(“*1”表示与构成链状结构或环状结构中的碳‑碳不饱和键的碳原子或三级碳原子的键结键)等官能基,F2为基“‑C(R7)=N‑”等官能基,F3为基“‑Si(R8)2(OR9)”等官能基。
