Paper Title:
Preparation and Properties of Polyvinyl Alcohol/Polyvinyl Pyrrolidone Blend Films
  Abstract

A series of poly(vinyl alcohol) (PVA)/ Poly (vinyl pyrrolidone) (PVP) blend films with different weight ratio of PVA to PVP were prepared by solution-mixing method The morphological structures and characterized of the films were observed via scanning electronic microscopy (SEM), Differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR). DSC measurements showed that there was only one Tg for each blend and the values of Tg varied with the PVA content. This implies that the PVP/PVA blend is at least partially compatible. The formation of the hydrogen bonding between the PVP and PVA was identified by the FTIR spectra.
