Abstract

The process of saturation of high-density polyethylene and polyethylene terephthalate with suband supercritical freons and supercritical carbon dioxide was investigated for the first time. The subcritical freon R22 was shown to be absorbed by these polymers in much larger amounts compared to subcritical freon R410a, as well as supercritical R23 and carbon dioxide, which makes it promising for use in the processes of impregnation and sterilization of polymers.
