Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER, AND MODIFIED CONJUGATED DIENE-BASED POLYMER COMPOSITION
Document Type and Number:
Japanese Patent JP2014159579
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a modified conjugated diene-based polymer which has an excellent balance between a low hysteresis loss property and wet skid resistance when formed into a vulcanizate, has practically satisfactory abrasion resistance and fracture strength, and also is excellent in processability.SOLUTION: The method for producing the modified conjugated diene-based polymer comprises: a polymerization step of polymerizing a conjugated diene compound or copolymerizing the conjugated diene compound and an aromatic vinyl compound by using an alkali metal compound or an alkaline-earth metal compound as a polymerization initiator to obtain a conjugated diene-based polymer having an active terminal; and a modification step of reacting a compound, which is shown by formula (1), with the active terminal of the obtained conjugated diene-based polymer.
