The lamellar thickness of polyethylene crystals measured by electron microscopy following chlorosulphonic acid fixation is often lower than the expected value. Experiments indicate that this is the result of insufficient acid treatment : the electron beam interacts with poorly fixed crystals to reduce lamellar thickness. Thickness reduction is not recorded when polymer has been fixed for longer times
