Polyurethanes are the world's sixth most abundant synthetic polymer. The most of their production represent flexible polyurethane foams. At the end of their life-cycle they are often deposited on waste dumps, where they degrade under the influence of various environmental factors; photodegradation and hydrolysis are the main routes. In this paper is focused on the identification of volatile photodegradation product of polyurethanes modified by biodegradable filler using Solid Phase Microextraction (SPME) and Gas Chromatography linked to Mass spectrometry. The SPME method was selected in the experiment for its fastness, simplicity and environmental friendnes.
