An in situ gravimetric technique, employing an electrobalance, is described for determining the solubility and diffusivity of gases in polymers over extended ranges of temperature and pressure. Solubilities of CO 2 in polystyrene at 35ะC were measured as a test case; the results are in excellent agr
