Additional information

n-Vinylpyrrolidinone has a measured viscosity of 2.1 mPa-seconds at 20 °C and 1.7 at 50 °C (BASF 1985). These values are supported by values from several reliable secondary sources that include 1.9 mPa-seconds at 29.9 °C (Atovmyan, E.G., et. al. 1992) and 1.836 mPa-seconds at 65 °C.
