Glass Ball as Bullet Solubility System: Argon with Polystyrene (PS)
Components:
   (1) Polystyrene (PS); ; [9003-53-6]  NIST Chemistry WebBook for detail
   (2) Argon; Ar; [7440-37-1]  NIST Chemistry WebBook for detail

 Critical Evaluation:
        Only three papers1-3 have been published for the system PS—argon. The work of Schulz and Gerrens1 is inconsistent and should be excluded from further consideration. VietH et al.3 reported sorption isotherms and dual mode sorption parameters for the solubility in oriented and unoriented PS at the ambient temperature, whereas Dursill2 studied the solubility in PS above its glass transition temperature.

     Pressure dependence of solubility is given below based on the parameters of sorption isotherms obtained by Vieth et al.3

     Combined consideration of the results from Refs. 2 and 3 results in the enthalpy of sorption of argon in PS equal to -7.1 kJ/mol.
