Free Volume. The Langmuir sorption capacity, C , of the dual-mode sorption model 12 J 3) characterizes gas sorption in the non-equilibrium excess fiee volume of a glassy polymer. The total sorbed gas concentration in a glassy polymer, which is a summation of Henry s law dissolution (C ) and Langmuir type hole filling (C, ), is given by ... [Pg.99]

The solubility coefficient indicates the sorption capacity of a polymer with respect to a particular sorbate. The simplest solubility coefficient is defined by Henry s law of solubility, which is valid at low concentration values for most substances. For other combinations, such as CO2 in PET at high pressure, Henry s and Langmuir s laws must be combined. These are also discussed in Chapter 14. [Pg.90]
