Abstract
The spatial distribution of filler particles and their agglomeration depending on concentration and size was studied. In all cases, silica particles served as filler. The particle size varied over a wide range, from nanoparticles to glass beads, and therefore the filler particles have the same nature. An amorphous polymer (polysulfone) and a crystallizing polymer (polypropylene) were chosen as a matrix for comparison. The filler concentration over the cross-section of the samples was determined visually and by electronic chemical analysis. It was shown that with increasing particle size, the tendency to redistribute the concentration increases in such a way that the near-wall region becomes depleted of filler. This effect is more pronounced for high filler concentrations and for a crystallizing polymer compared to an amorphous one.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
