Multiplying the ratio of monomer consumed to the concentration of the CTA used by the molecular weight of the monomer ( mM ) a reliable estimate of the number average molecular weight can be determined.

Using techniques such as determinations of elemental analysis, average molecular weight, end-group analysis, and examination of products, Marvel demonstrated a chemical methodology for establishing the principal structural features of polymers.

The size distribution can be characterized statistically by its weight average molecular weight ( Mw ) and its number average molecular weight ( Mn ), the ratio of which is called the polydispersity index ( Mw / Mn ).

The feedstock to an FCC is usually that portion of the crude oil that has an initial boiling point of 340 �C or higher at atmospheric pressure and an average molecular weight ranging from about 200 to 600 or higher.

To measure the average molecular weight directly without calibration from the light scattering intensity, the laser intensity, the quantum efficiency of the detector, and the full scattering volume and solid angle of the detector needs to be known.
