T/K	Chemical Name	Henry's law constant, K [cm³(STP)/cm³ atm]	Langmuir's parameter, C_H [cm³(STP) cm^-3]	Affinity Coefficient b [atm^-1]
293	CO2	0.801	13.0	0.184
303	CO2	0.713	11.0	0.134
313	CO2	0.586	8.81	0.0918
293	CH4	0.305	5.00	0.0811
303	CH4	0.277	4.93	0.0623
313	CH4	0.244	3.63	0.0439

Method/Apparatus/Procedure:
   Equilibrium sorption was measured by the pressure decay method in the cell similar to that described in ref. (1). The pressure in the cell was continuously measured by a pressure transducer.

Source and Purity of Materials:
   PS films provided by Mitzubishi -Monsanto Chemical Co were studied.

Estimated Errors:
