METHOD FOR PRODUCING DENATURED CONJUGATED DIENE POLYMER

摘要

Provided is a method for producing a denatured conjugated diene polymer capable of being used in vehicle tires and such, and as a starting material for a cross-linking polymer capable of improving the fuel economy performance of vehicles and the like. A method for producing a denatured conjugated diene polymer includes a polymerization step for obtaining a denatured conjugated diene polymer by polymerizing a monomer containing a conjugated diene compound, or a monomer containing a conjugated diene compound and an aromatic vinyl compound, with at least one type of compound selected from a group consisting of formula (1) and formula (2), while in the presence of an alkali metal compound or an alkali earth metal compound. (In the formula, A1 represents a hydrocarbyl silyl group in which each of the three hydrogen atoms (H) in the [-SiH3] structure is substituted by a hydrocarbyl group; and R1 and R2 represent a hydrocarbylene group.)
