Cyclic oligomers [CO. C6H 4 β’ CO. O. CH 2 β’ CH 2 β’ O]x (with x = 3-8) of poly(ethylene terephthalate) have been prepared by a polymer-supported reaction. They have been investigated by field desorption mass spectrometry and liquid chromatography/mass spectrometry. The particular stability of the cyc
