The fracture behaviour of isotropic and oriented polyethylene has been combined with studies of the internal microstructure using optical and electron microscopic observations of permanganic etched samples. Very considerable differences in fracture toughness were obtained for oriented polymers of different molecular weight or degree of branching, and it has been found that there are corresponding differences in morphology
