Polyvinylcarbazole (PVK) is a temperature-resistant[2] thermoplastic polymer produced by radical polymerization from the monomer N-vinylcarbazole.

[3] Polyvinylcarbazole was discovered by the chemists Walter Reppe (1892-1969), Ernst Keyssner and Eugen Dorrer and patented by I.G.

It can be produced by suspension polymerization at 180 °C with sodium chloride and potassium chromate as catalyst.

[2] It is used in insulation technology,[2] electrophotography (e.g. in copiers and laser printers),[3] for the fabrication of polymer photonic crystals,[6] for organic light-emitting diodes and photovoltaic devices.

[1] In addition, PVK is a well researched component in photorefractive polymers and therefore plays an important role in holography.
