Thermal and FTIR Characterization of Poly (4-vinylpyridine) Crosslinked with Metal Salts

Abstract

We investigated the physical properties and degree of crosslinking of poly (4-vinylpyridine) (P4VP) blended with transition metal salts using differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). The glass transition temperature (Tg) of the blends increased significantly upon addition of zinc (Zn) and copper (II) (Cu) salts. Tg enhancement was found to be highly dependent upon the type and loading of the metal salt. A maximum increase of 70 degrees C was observed at 0.25 molar equivalents of Zn cation. Ash content from TGA was highest for the 0.25 zinc salt loading, indicating that the maximum amount of metal ion was incorporated into the polymer at this concentration. Fourier transform infrared spectroscopy (FTIR) provided confirmation that transition metal coordination between the Zn cation and the pyridine nitrogens occured, and allowed for the quantification of pyridine binding.
