The Aqueous Conformation and Solubility of Polyvinylpyrrolidone in Relation to the Use of Polymers in Oil Recovery
Polyvinylpyrrolidone (PVP) (monomer-unit structure [I]) is a water-soluble synthetic polymer which is stable physically and chemically in aqueous solution (1–3), and which is commercially available in a diversity of molecular weight grades (4). From these features alone, PVP has potential for use in oil-recovery and related applications; similarly, its monomer unit has potential as a component of copolymers tailored for these applications (5). In any such applications, it is important not only that the polymer remains in solution under all conditions of temperature, pressure and salinity that may be encountered, but that its solutions also retain the desired rheological behavior. Ensuring that this happens, especially with novel copolymers, requires that we have a good understanding of the molecular interactions which occur in these aqueous polymer systems.
