    Abstract

    The study of thermal properties and photooxidation of high styrene-butadiene copolymer (SBC) with high styrene content (K-resin) using a variety of analytical and spectroscopic methods including yellowness, luminescence and FTIR spectroscopy. It was observed that the FTIR and luminescence analysis show complex oxidation processes with some distinct features associated with each phase. It was shown that the rates of thermal oxidation on oven ageing increases carbonyl growth with increasing temperature. The autocatalytic growth and decay of hydroperoxides at 110 and 90°C with high concentrations being observed at 90°C were observed.
