Heterogeneity of accelerated photooxidation in commodity polymers stabilized by HAS: ESRI, IR, and MH study
Original language description
Heterogeneity of the photooxidation processes in plaques made of four commodity polymers, polypropylene (PP), polyethylene (PE), polystyrene (PS) and poly(ethylene-co-norbornene) (Topas, TP) stabilized with hindered amine stabilizer (HAS) were studied using Electron Spin Resonance Imaging (ESRI) and three independent microscopic-scale methods: scanning electron microscopy (SEM), infrared microscopy (IR) and microhardness (MH). Concentration profiles of nitroxides mapping photooxidation process inside polymer plaques along the direction perpendicular to their surface were determined by electron spin resonance imaging technique (ESRI) in dependence on the duration of accelerated photooxidation. We present data characterizing stabilization activity of Chimassorb 119, Chimassorb 944, Tinuvin 770 in combination with UV stabilizer Tinuvin 320 or Tinuvin 327, nitroxide HAS Prostab 5415, and alkoxyamine derivative of HAS Tinuvin NOR 371 and compare them with the previously published data.
