The solid phase catalytic oxidative degradation of isotactic polypropylene was studied. The influences of the type and amount of catalyst, temperature, and type of oxidising agent on the oxidative degradation were investigated. Iron(III), manganese(II), cobalt(II), vanadium(III), copper(II) and nickel(II) acetylacetonates were used as catalysts. The obtained products were characterised by the determination...
Spatial resolution of photo and thermooxidation processes in polypropylene (PP) and polystyrene (PS) plaques was studied by electron spin resonance imaging (ESRI) and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR FTIR). Polymer plaques made of PP and PS stabilized with various systems based on hindered amine stabilizers (HAS) were exposed to accelerated photodegradation...
