Method for preparing solution polymerized rubber/white carbon black composite material with end containing carboxyl

The invention provides a method for preparing a solution polymerized rubber/white carbon black composite material with end containing a carboxyl functional group. The solution polymerized rubber/white carbon black composite material is prepared by performing a chemical reaction of the end functional group and carboxyl on the surface of white carbon black. The method can greatly reduce the agglomeration of white carbon black in a polymer, and reduce the phase separation of the polymer and white carbon black from a molecular level, strong interacting effect of white carbon black and a polymer matrix is enhanced, so that the comprehensive performance of the material is effectively improved. During the preparation method of the composite material, traditional heavy mixing equipment during rubber processing is not required, and high energy consumption and mixed reinforcing treatment are reduced. 本发明提供了种末端含有羧基官能团的溶聚橡胶/白炭黑复合材料的制备方法，利用末端官能团与白炭黑表面的羟基进行化学反应制备溶聚橡胶/白炭黑复合材料。该方法能较大地减弱白炭黑在聚合物中的团聚现象，并从分子水平减小聚合物与白炭黑的相分离，同时通过加
