DSC compares the heat flow between the sample tested and that of an empty reference sample pan, and reveals many thermal characteristics of a sample. The DSC thermal responses of a material that are most important for our research were the identification of a sample's Tg and melting temperature Tm. If the Tgs and Tms observed are close to those observed in neat PVC and neat U and/or U related compounds, then it is assumed that no complex has formed.
