Water-soluble polymers serve a wide variety of functions, being used in water treatment, food processing, mineral processing, cosmetics, and pharmaceuticals. Water-soluble polymers often contain modifiable pendant groups that have found immense use of building new families of polymers with new and interesting properties. The synthesis of a novel water-soluble polymer, polyvinyl pyrrolidone-polyvinyl alcohol (PVP-PVOH) of various molecular weights and copolymer compositions are described. The objective of this study is to synthesize and analyze PVP-PVOH copolymers and blends of PVP and PVOH. The properties of these copolymers and blends are analyzed through Differential Scanning Calorimetry (DSC), Proton Nuclear Magnetic Resonance Spectroscopy (NMR), Elemental Analysis (EA), DNDC (specific refractive index increment), and Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR). We report on the methodologies used to determine % PVP present in these copolymers and blends as well as the determination of physical properties such as glass transition temperature. The PVP-PVOH copolymers had PVP content ranging from 30 to 70 mole %.
