Abstract: Compatibility in polymer compounds is determined by the kinetics of mixing and chemical affinity. Compounds like reinforcing filler/elastomer blends display some similarity to colloidal solutions in that the filler particles are close to randomly dispersed through processing. Applying a pseudo-thermodynamic approach takes advantage of this analogy between the kinetics of mixing for polymer compounds and true thermally driven dispersion for colloids. The results represent a new approach to understanding and predicting compatibility in polymer compounds based on a pseudo-thermodynamic approach.
