Method/Apparatus/Procedure:
   Sorption measurements were performed using a vacuum electronic microbalance (Sartorius Instruments).

Source and Purity of Materials:
   CEVA containing 45 wt.% of vinyl acetate with Mw = 37,700 from Bayer Co and CPE (Hypalon 48) from DuPont, UK obtained by sulphochlorination of PE having Mn = 23,900 (Cl content 44 wt.%) were studied. A small but not specified content of SO2Cl groups in CPE is possible. Both polymers were shown by X-ray diffraction to be amorphous. Some phase separation is reported for the blends with CEVA content lower than 50 % (DSC data).
