👉 Polyvinylpyrrolidone (PVP) is a synthetic polymer that has been extensively used in various applications due to its high melting point, low viscosity and excellent mechanical properties. It is also known as Polyvinyl Phthalate or PVP. In the context of polyvinylpyrrolidone, it can be defined as a type of polymer that is composed of two monomers: ethylene glycol (EG) and pyrrolidine (PYR).
