The chain orientation, induced by hot drawing, decreases the sorption capacity of polystyrene due to the tighter packing of macromolecules in the oriented material. Density measurements and decay of birefringence indicate that the loss of orientation is a much more rapid phenomenon than the thermal shrinkage of the polymer.

Abstract
The chain orientation, induced by hot drawing, decreases the sorption capacity of polystyrene due to the tighter packing of macromolecules in the oriented material. Density measurements and decay of birefringence indicate that the loss of orientation is a much more rapid phenomenon than the thermal shrinkage of the polymer.File in questo prodotto:
