We have investigated the use of the viscometric method for measuring the Flory interaction parameters for dilute polystyrene solutions in a range of solvents. Two 'single point' methods were used to estimate the intrinsic viscosity and these agreed well with the more conventional method of extrapolating results over a range of concentrations. Also, the interaction parameters derived from these intrinsic viscosity values showed good agreement with literature results. Values of the Flory interaction parameters are presented for 11 solvents, some of which have not previously been published
