Poly(ethy1ene terephthalate) was exposed to radiation from different kinds of low-pressure plasmas in an oxygen atmosphere. The lower wavelength limit of the spectrum investigated, X = 112 nm, is the cut-off of magnesium fluoride used for separating the specimen chamber from the plasma light source.
## Abstract Poly(ethylene terephthalate) (PET) was degraded in a two step process to obtain a valuable oil, consisting mainly of benzene. First, PET was hydrolyzed in a steam atmosphere at 450°C, and the resulting terephthalic acid was decarboxylized in the presence of CaO. By separating the two fu
