Abstract
Field desorption mass spectrometry (FD-MS) has been evaluated for the analysis of low molecular weight polyethylene by using samples in the molecular weight range 600-2000 u as determined by gel permeation chro matography. The repeat units and end groups were characterized by FD-M S, but it was demonstrated that accurate molecular weight distribution data cannot be obtained for polyethylene by FD-MS because there is ma ss discrimination against the higher molecular weight polymers.
