Characterization and preparation of Polyvinyl Alcohol (PVA) as inhibitor in formation of hydrates

The thermal properties of PVA with different degree of hydrolysis (DH) was studied by preparation of aqueous polymer solution, followed by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). The DSC result showed the typical p...
