[Absorption of ethylene oxide by medical polymers]

The balanced sorption of a sterilizing gas--ethylene oxide (EO)--by medical polymers most commonly used in medical industry is studied. These polymers are compositions on the base of polyvinylchloride (PVC), polyethylene (PE), natural and silicone rubbers. The absorption coefficients for EO and the above materials are calculated. The most sorption capacity is inherent in the PVC-based compositions and the least one--in the PE-based materials. The latters as well as silicone rubber materials are recommended for medical engineering products subjected to gaseous sterilization.
