Dilute solution properties of flexible polymers in toluene: A comparison of commercially available photometers

Dilute solution properties of polystyrene and poly(α‐methylstyrene) in toluene have been measured using several of the commercially available instruments for intensity light scattering. Results are compared among the instruments used and with literature values. Relative advantages and disadvantages of the instruments are discussed. Copyright © 1991 John Wiley & Sons, Inc.
