Provided 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 of producing a modified conjugated diene-based polymer, a modified conjugated diene-based polymer obtained by the production method, a rubber composition using the polymer, and a pneumatic tire. The modified conjugated diene-based polymer has excellent low heat generating property and abrasion resistance, and the rubber composition is obtained by using the modified conjugated diene-based polymer and the pneumatic tire is obtained by using the rubber composition.
提供了一种修饰剂,该修饰剂是通过将具有受保护的一级氨基和至少两个可水解基团的含硅化合物进行完全缩合而获得的;一种生产改性共轭二烯基聚合物的方法;通过生产方法获得的改性共轭二烯基聚合物;使用该聚合物的橡胶组合物;以及气动轮胎。改性共轭二烯基聚合物具有优异的低热发生性和耐磨性,橡胶组合物是通过使用改性共轭二烯基聚合物获得的,气动轮胎是通过使用橡胶组合物获得的。
