About this document
Intrinsic Viscosity and MW of Polystyrene by Nouran Shedid is a document available to read on EtoBox.
The document describes a laboratory experiment to determine the intrinsic viscosity and molecular weight of polystyrene using viscosity measurements. Various concentrations of polystyrene in toluene were prepared and their flow times through a Cannon-Fenske capillary viscometer were measured. The intrinsic viscosity was calculated by extrapolating the reduced viscosity to zero concentration using the Mark-Houwink equation. The experiment found the intrinsic viscosity of polystyrene to be 51.78 cm3/g and its
