Disclosed are a modifying agent obtained by subjecting a silicon-containing compound having a protected primary amino group and at least two hydrolyzable groups to complete condensation, a method for producing a modified conjugated diene polymer, a modified conjugated diene polymer obtained by the production method, a rubber composition comprising the modified conjugated diene polymer, and a pneumatic tire. The modified conjugated diene polymer has excellent low-heat-generating properties and abrasion resistance, and the rubber composition is obtained using the modified conjugated diene polymer and the pneumatic tire is obtained using the rubber composition. |
