摘要:

The birefringence of solvent-cast atactic polystyrene films was measured as a function of annealing temperature. The birefringence was found to disappear at a temperature which corresponds to the liquid-liquid transition, as measured by differential scanning calorimetry. It is concluded that this experiment is a proof of the molecular origin of the liquid-liquid transition.
