摘要: A method is developed by which polymer molecular weight and its distribution can be accurately determined deconvolution of dynamic melt viscoelastic properties in the terminal plateau zones. The illustrated with a series monodisperse (narrow-distribution) polydisperse (broaddistribution) polystyrenes. Mn, Mw, Mn/Mw values obtained are excellent agreement those light scattering, osmometry gel permeation chromatography less than 5 to 10 percent error. differential molecular-weight curves coincide wall chromatography. applicable insoluble as well soluble polymers.
