変性共役ジエン系重合体およびその製造方法

Document Type and Number:

Japanese Patent JP4316004

Kind Code:

B2

Abstract:

A modified conjugated diene polymer comprises a modifying group based on a low molecular weight compound having two or more tertiary amino groups and one or more alkoxysilyl groups in a molecule which bonds to a conjugated diene polymer obtained by polymerization of a conjugated diene compound or a conjugated diene polymer obtained by copolymerization of a conjugated diene compound and an aromatic vinyl compound. The process for producing the modified conjugated diene polymer comprises the steps of: polymerizing a conjugated diene compound or copolymerizing a conjugated diene compound and an aromatic vinyl compound in a hydrocarbon solvent using an alkali metal initiator and/or an alkaline earth metal initiator; and reacting active terminals of the resulting polymer with a low molecular weight compound having two or more tertiary amino groups and one or more alkoxysilyl groups in the molecule.
