Method/Apparatus/Procedure:
Volumetric method by Meares

was used. The sample was allowed to equilibrate with a gas, then nonsorbed gas was swiped away with mercury. The volume of gas subsequently desorbed from the sample was measured by means of McLeod gauge.
Source and Purity of Materials:
PVC from ICI (99 % "pure") in a form of powder was studied. The plasticized sample contained 0.325 mol fraction of tricresyl phosphate. Films were prepared by calendering after adding 2 parts of cadmium stearate and 0.2 parts of stearic acid per 100 parts of the polymer.
Estimated Errors:
