Abstract The post-yield behaviour of linear low-density and high-pressure polymerized low-density polyethylenes have been compared in tension and compression. Rubber elasticity theory has been used to describe the strain-hardening region of the stress-strain curves in terms of extension of amorphous regions and entanglement associated with crystalline regions. The resulting strain-hardening functions were used to predict the geometry of the neck profiles produced while deforming in tension. No relationship between strain hardening and environmental stress-crack resistance was found in that the two types of polyethylenes exhibited very different dependences.
