Dispersion of a filler in the rubber blend. Part II. Methods of dispersion degree assessment

In the review (83 references) the methods useful for assessment oi dispersion degree of filler in a rubber matrix were presented. Systematic discussion of the methods, grouped from the phenomena and properties of the systems tested points of view, has been done. It was marked that dispersion degree of filler is a resultant of agglomeration/aggregation and uniformity of a filler distribution in rubber matrix. On the basis of the results of investigations carried out using modern measuring techniques the possibility of effect of agglomerate structure on physical properties of a rubber was indicated. Several mathematic models applied for evaluation of dispersion degree of filler were also presented.
