The EPDM phase was preliminary loaded with varying amounts of vulcanization agents followed by the reactive blending with PP matrix on a roll mill at 185 o C. The samples were extruded through a capillary rheometer at 185 o C. It is demonstrated that even at low shear rate the convergent flow results in strong coalescence efficacy of droplets in raw blends and in complete suppression of coalescence at low Nc.</p></abstract><trans-abstract xml:lang="ru"><p>а примере смесей 20/80 СКЭПТ/ПП исследовано влияние степени сшивания (Nc) дисперсной фазы СКЭПТ на коалесценцию ее частиц в процессе капиллярной экструзии. Фазу СКЭПТ с предварительно введенными в нее различными количествами вулканизующих агентов подвергали реакционному смешению с матрицей ПП на вальцах при 185 o C. Образцы экструдировали с использованием капиллярного реометра при 185 o C и постоянной скорости сдвига. Показано, что даже при низкой скорости сдвига конвергентный поток приводит к сильной коалесценции капель в невулканизованных смесях и к полному ее подавлению уже при низких значениях Nc.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mackay, G.D.M.
