It would be beneficial to perform further research on the effects of different concentrations of U and its related compounds on the PVC-complexes' Tgs, because this could result in the discovery of a more sustainable and less toxic plasticizer. To determine whether our goal of lowering PVC's Tg had been achieved by the complexed PVCs, DSC and FTIR were utilized to analyze the samples made with PVC and U, and/or U related complounds, and mechanical property measurements were made on their films to learn if they were softer than neat PVC.
