The use of GPC coupled with a multiangle laser light scattering photometer for the characterization of polymers. On the determination of molecular weight, size and branching

摘要: The use of gel permeation chromatorgraphy (GPC) coupled with the multiangle laser light scattering (MALLS) detector for determination molecular weight and size distribution identification polymer branching is demonstrated on several examples both organic water souluble polymers. influence second virial coefficient way data evaluation results obtained shown. Measurements root mean square radius are presented two series polystyrene polymethylmethacrylate standard, compared radii calculated from Flory-Fox equation. © 1994 John Wiley & Sons, Inc.
