The CO//2 solubility in oriented and unoriented atactic polystyrene films has been investigated. Orientation does not change the nature of the sorption process; however, it decreases the level of solubility. Both the Langmuir sorption term and the Henry's-law contribution are affected by orientation. The decrease of solubility is correlated with an increase of density due to orientation. A simple experiment has been described to evaluate the depression of the glass transition temperature of polystyrene containing dissolved carbon dioxide.

Both the Langmuir sorption term and the Henry's-law contribution are affected by orientation. The decrease of solubility is correlated with an increase of density due to orientation. A simple experiment has been described to evaluate the depression of the glass transition temperature of polystyrene containing dissolved carbon dioxide.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
