Thermal decomposition studies on polyurethane elastomers reinforced with polyhedral silsesquioxanes by evolved gas analysis

Furthermore, the inclusion of POSS in the PU network directly influences the degradation pathways of both the soft and hard block components of the elastomers - it has been observed that the POSS/PU hybrid systems show reduced levels of CO2 and changed levels of characteristic ion fragments, e.g. m/z 42 related to hydrocarbons and THF.
