Abstract
The square-root method of treating light-scattering data on narrow-distribution polymers in dilute solution ceases to be effective for samples of very high molecular weight in good solvent unless the experimental data are obtained down to a fairly small scattering angle (of the order of 10°). This communication reports the development of a new method which is expected to be particularly useful for such polymer-solvent systems, on the basis of recent experimental evidence that the particle scattering factor P(θ) is little affected by the long-range interference between chain segments and follows quite closely the Debye equation for Gaussian chains. The potentiality of the method is demonstrated with data on polyisobutylene in cyclohexane and those on poly(α-methylstyrene) in benzene.
