Abstract
Single crystals of polyethylene are investigated by transmission electron microscopy. The observed effects suggest that in polyethylene screw dislocations exist, the Burgers vector of which is parallel to the chain molecules. The dislocation densities were between 108 and 1010 cm−2. Evidence for the splitting of the observed dislocations into two partial dislocations is presented.Keywords
