Thermal stability of poly(vinyl chloride)/polyurethane blends

Abstract The thermal stability of poly(vinyl chloride) (PVC) and thermoplastic polyurethane (PU) blends has been studied in this work. It has been found that the PVC/PU blends possess lower thermal stability than unmodified PVC. No effect of the structure of polyurethanes or their content on the stability of PVC/PU system has been found.
