Description
  • Představujeme model morfologického vývoje částic polyolefinů v katalytických polymeračních reaktorech. Model předpokládá, že se částice skládá z velkého počtu mikro-elementů s visko-elastickými interakcemi působícími mezi mikro-elementy. Jsou prezentovány výsledky systematického mapování z parametrického prostoru aktivity katalyzátoru, reakčních podmínek, odporu proti transportu hmoty a visko-elastických vlastností polyolefinů do prostoru možných morfologických vývojů, jako je vytváření dutých částic, částic s makro-kavitami, pravidelná nebo nepravidelná replikace tvaru částic během jejich růstu, tvorba prachových částic atd. Predikované morfologie částic jsou porovnány s experimenty. (cs)
  • We have introduced the model of the morphological evolution of polyolefin particles in catalytic polymerization reactors. The model considers the polyolefin particle to consist of a large number of microelements with viscoelastic interactions acting among them. Here we present the results of the systematic mapping from the parametric space of catalyst activity, reaction conditions, mass transport resistance, and viscoelastic properties of polyolefins into the space of possible morphological developments, such as the formation of hollow particles, particles with macrocavities, regular or irregular replication of particle shape during its growth, highly porous or compact particles, the formation of fine particles, etc. The predicted particle morphologies are compared with experimental findings.
