Thermal expansion of oriented polyethylene | SpringerLink

It is shown that the sign of the linear coefficient of thermal expansion is determined by the configuration and direction relative to the deformation axis of the molecular chains in the amorphous and crystalline phases of the polyethylene. An increase in orientation leads to a decrease in shrinkage temperature.
