The thermal diffusivity of Poly(N-vinyl-2-pirrolidone) (PVP) samples was investigated using open photoacoustic cell technique (OPC) as function of molecular weight and crosslinking. Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X ray diffraction (XRD) techniques were also used to the PVP characterization.
