ABSTRACT
Osnovni postupak pridobivanja PS-E-a je suspenzijska polimerizacija stirena. U tom je postupku organska faza (stiren monomer) suspendirana u vodi u obliku kapljica. Stabilnost suspenzije ovisi o raznim faktorima: čistoći sirovina i aditiva, brzini polimerizacije, omjeru monomera i vode, brzini vrtnje miješalice, geometriji reaktora i dr. U radu se opisuje tehnologija dobivanja PS-E-a u DIOKI-ju jednostupnjevitom polimerizacijom baziranom na tehnologiji PSTW (SAD). / Suspension polymerization of styrene is the main process for PSE production. In this process organic phase (styrene monomer) is suspended in water phase as droplets. Stability of suspension depends on various factors: purity of raw materials and additives, polymerization reaction rate, ratio monomer/water, mixing speed, reactor geometry and other. The paper describes production technology for PS-E in DIOKI with one step production based on PSTW technology (USA).
