摘　　要：　键合橡胶的形成源于SiO2的表面与聚硅氧烷发生强烈相互作用。它具有三维结构,其形成过程是一个复杂的动力学机制。本文根据Meissner、Cohen Addad以及Leblanc等理论,描述了键合橡胶的链吸附与缠结机理,讨论了SiO2增强粒子的加入对聚硅氧烷体系的流变特性的影响。The formation of the bound rubber was induced by the strong interactions between the surface of silica and polysiloxane. There exists a spatial three-dimensional characteristic in the structure of bound rubber, and its formation deals with a complicated kinetic mechanism. The mechanism of chain adsorption and entanglement of the bound rubber were reviewed with 47 references. The influences of filled silica on the rheological properties of polysiloxane were discussed also.
