Abstract A simple micro-method for the determination of molecular weights of chondroitin sulphate has been developed. Columns of Sephadex G-200 and Sepharose 6B were calibrated with fractions of chondroitin sulphate, the molecular weights of which had been determined by independent methods.

Determination of molecular weight dependences and characterization of molecular weight distributions
European Polymer Journal, 1982Abstract Molecular weight dependences of the square of the radius of gyration as well as of the coefficients of diffusion and friction of monodisperse polystyrenes in toluene at 20°C are determined experimentally. For this purpose, the z-averages of these quantities and M w as determined by light scattering were subjected to the polydispersity ...

Ratios of average molecular weights and molecular weight distributions in polymers
Journal of Polymer Science: Polymer Physics Edition, 1979AbstractIf Mmin and Mmax are lower and upper bounds, respectively, to the molecular weights of different molecular weight species contained in a polymer, the weight‐average to number‐average molecular weight ratio Mw/Mn cannot exceed (1 + Mmax/Mmin)2/(4Mmax/Mmin).

Modality of molecular weight distributions
Polymer Engineering & Science, 1990AbstractEven restricting attention to weight distributions, it is ambiguous to merely say that a polymer is “not bimodal.” A simple example is shown wherein the weight distribution of log (molecular weight) is bimodal, but the weight distribution of molecular weight is not bimodal.
