## Abstract The ability of different metal oxides and acetates to catalyze the thermal degradation of poly(pivalolactone) into cyclic oligomers has been investigated. Magnesium oxide was found to be the most active catalyst which converts poly(pivalolactone) completely into oligomers within less th

## Abstract The thermal and electron impact induced degradation reactions of poly(ε‐caprolactone) {poly[oxy(1‐oxohexamethylene)]} were investigated in a mass spectrometer. It can be shown that the favorated thermal degradation reaction is the cleavage of the ester bond and formation of ω‐hydroxyl a
## Abstract Pyrolysis‐mass spectra have indicated that polypivalolactone degrades thermally into cyclic oligomers. To confirm this degradation behaviour polypivalolactone was pyrolyzed in a glass apparatus and the degradation products trapped at 0°C. After separation by preparative gel chromatograp
