Molten low-density polyethylene is a good stationary-liquid-phase for gas-liquid chromatography, but its performance deteriorates with prolonged use at high temperature (ca 250°C). This change in behaviour is interpreted in terms of scission at the branch points of the polyethylene. Gel-permeation chromatograms of the polyethylene recovered from the GLC supporting material provide evidence for this interpretation, and indicate that scissions of (at least) the short-chain branches are occurring… CONTINUE READING
