Title:
変性共役ジエン系重合体及びその製造方法
Document Type and Number:
Japanese Patent JP5871011
Kind Code:
B2
Abstract:
A method for producing a modified conjugated diene polymer which can be used as a raw material of a cross-linked polymer used for use in automobile tires and the like, in order to enhance low fuel consumption performance is provided. A method for producing a modified conjugated diene polymer comprising a step of polymerizing a monomer comprising a conjugated diene compound and the like in the presence of a compound represented by the following formula (1) or (2) and an alkali metal compound to obtain a conjugated diene polymer, and a step of reacting the conjugated diene polymer and a compound represented by the following formula (3) to obtain a modified conjugated diene polymer. (In the formulae, R 1 is a hydrocarbylene group. Q is, for example, -N(-A 1 )-. A 1 is a hydrocarbyl group which has no active hydrogen atom and may be substituted with an atom such as N.) (In the formula, E is, for example, a functional group which has no active hydrogen atom and is bound by an atom of N to R 4 . R 2 and R 3 are hydrocarbyl groups. R 4 is a hydrocarbylene group. n is an integer of 0 to 2.)
