CONJUGATED DIENE POLYMER PRODUCTION METHOD, AND CONJUGATED DIENE POLYMER COMPOSITION PRODUCTION METHOD

Title:

CONJUGATED DIENE POLYMER PRODUCTION METHOD, AND CONJUGATED DIENE POLYMER COMPOSITION PRODUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2013/118787

Kind Code:

A1

Abstract:

The present invention relates to a conjugated diene polymer production method in which a compound represented in formula (1) is used to polymerize a monomer component containing a compound represented by formula (2), a compound represented by formula (3), and a conjugated diene compound, and the active end of the polymer generated by polymerization is reacted with a compound containing a nitrogen atom and/or a silicon atom. (In formula (1), R11 represents a hydrocarbylene group having 6-100 carbon atoms, R12 and R13 represent hydrocarbyl groups optionally having a substituent group, or, a trihydrocarbylsilyl group, or, R12 is bonded to R13 and the group by which R12 is bonded to R13 is a hydrocarbylene group optionally containing a nitrogen atom and/or an oxygen atom as hetero atoms, a group having 5-20 carbon atoms represented by -Si(R14)2-(CH2)x-Si(R14)2- (wherein R14 represents a hydrocarbyl group and x represents an integer 1-10), or a group having 4-20 carbon atoms represented by -Si(R15)2-(CH2)y- (wherein R15 represents a hydrocarbyl group and y represents an integer 2-11), and M represents an alkali metal atom.) E2-A2 (2) (In the formula, E2 represents a hydrocarbyl group having a polymerizable carbon-carbon double bond, and A2 represents a substituted amino group or a nitrogen-containing heterocyclic group.) E3-A3 (3) (In the formula, E3 represents a hydrocarbyl group having a polymerizable carbon-carbon double bond, and A3 represents a substituted silyl group.)
