The phase specific localization of the reinforcing fillers like carbon black (CB), which has been known to influence the physical and mechanical performance of the rubber blends, can be determined by different characterization techniques, however, only for binary rubber blends. They have been failed so far when applied for more complicated systems like filled ternary rubber blends. In the present work we introduced a new technique using the attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) with germanium crystal for characterization of the specific localization of CB in a ternary blend of solution styrene butadiene rubber (SBR), butadiene rubber (BR) and natural rubber (NR). It is the first time we could follow the change of the amount of CB localized in each phase of this blend along the mixing time. CB firstly is incorporated into the NR phase and then it obviously migrates from the NR phase to the SBR phase as a function of mixing time that corresponds very well with the theoretical prediction based on the Z-model using the surface tension values of the filler and rubber blend components. The interaction between CB and rubber components can be qualitatively proved by the shift of the FTIR peak. Thermogravimetric analysis (TGA) was used to support the results obtained by the FTIR method. The study was further extended to follow the CB distribution in multi-step mixing.

可以通过不同的表征技术确定增强填料（如炭黑（CB））的相比局部化，而炭黑（CB）会影响橡胶共混物的物理和机械性能，但是，只能通过二元橡胶共混物来确定。迄今为止，当它们用于更复杂的系统（如填充的三元橡胶混合物）时，它们已经失败了。在当前的工作中，我们介绍了一种使用衰减全反射傅立叶变换红外光谱（ATR - FTIR）的新技术。）和锗晶体，以表征溶液丁苯橡胶（SBR），丁二烯橡胶（BR）和天然橡胶（NR）的三元共混物中CB的特定位置。这是我们第一次可以追踪到这种混合物在每个相中沿着混合时间变化的CB量的变化。CB首先被掺入NR相中，然后明显地随混合时间从NR相迁移到SBR相，这与基于Z模型的理论预测非常吻合使用填料和橡胶共混物组分的表面张力值。CB和橡胶组分之间的相互作用可以通过FTIR峰的移动来定性地证明。使用热重分析（TGA）来支持通过FTIR方法获得的结果。进一步扩展了研究，以遵循多步混合中的CB分布。
