MODIFIED CONJUGATED DIENE-BASED POLYMER AND PRODUCTION METHOD

In a modified conjugated diene-based polymer, a ratio of a coupling polymer, obtained by gel permeation chromatography (GPC), is 70% by mass or more based on a total amount of the modified conjugated diene-based polymer, and a modification ratio obtained by adsorption GPC is 70% by mass or more base...

Beschreibung
Zusammenfassung:	In a modified conjugated diene-based polymer, a ratio of a coupling polymer, obtained by gel permeation chromatography (GPC), is 70% by mass or more based on a total amount of the modified conjugated diene-based polymer, and a modification ratio obtained by adsorption GPC is 70% by mass or more based on a total amount of the modified conjugated diene-based polymer, and when Mooney viscosity ML 1+4 (100°C) measured at 100°C is represented by ML and a weight average molecular weight obtained by GPC is represented by Mw, ML ¤ 1.8 (Mw × 10 -4 ) - 31.5, and Mooney viscosity ML 1+4 (100°C) measured at 100°C is 30 to 150.
