The invention discloses a method for preparing silicon dioxide with poly (conjugated diene) grafted on the surface and a poly (conjugated diene) elastomer filled with silicon dioxide filler. The method comprises the following steps: uniformly mixing an initiator, a ligand, a metal catalyst, a conjugated diene monomer and a solvent, optionally adding a reducing agent, and carrying out atom transfer radical polymerization, the poly conjugated diene elastomer filled with the silicon dioxide filler has the characteristics of low heat generation, low-temperature performance and excellent mechanical performance, and can be used for high-performance winter tires.

    本发明公开了一种制备表面接枝聚共轭二烯烃的二氧化硅的方法以及二氧化硅填料填充的聚共轭二烯烃类弹性体。所述方法包括将引发剂、配体、金属催化剂、共轭二烯单体和溶剂混合均匀,任选地加入还原剂,进行原子转移自由基聚合,其中引发剂为硅烷偶联剂改性二氧化硅。所述二氧化硅填料填充的聚共轭二烯烃类弹性体具有低生热、低温性能和机械性能优异的特点,可用于高性能冬季胎。
