Determination of molecular weight distribution of polyacrylonitrile
May 28th 2010A separation based on molecular size using GPC with organic eluents was demonstrated, along with a simple sample preparation procedure. Since this GPC application uses DMF and a small amount of lithium bromide as mobile phase, it will work on a standard HPLC system without any modifications. The molecular weight ranges (Mw) of the polyacrylonitrile samples analyzed were found to be in the middle of the linear calibration range.
