Due to their interesting properties, zwitterionic polymers have been extensively studied; however, only a few reports discuss their thermal degradation. The objective of this work was to study the pattern of thermal degradation of three poly-(sulfobetaines) with different lateral chain lengths and t

β¦ Synopsis
The thermal stability of poly(acenaphthylene) has been studied by pyrolysis gas-liquid chromatography and pyrolysis mass spectrometry. The principal degradation product is acenaphthylene monomer, with smaller amounts of a similar compound, possibly the saturated acenaphthene. Small yields of a dimeric oligomer were also observed. Mechanisms for product formation are suggested.

The thermal degradation of poly(o-acetylstyrene) (POAS) was studied at 390Β°C under high vacuum. The principal reactions are removal and decomposition of acetyl groups, depolymerization, random chain scission and oligomer formation. The degradation mechanism resembles that of polystyrene (PS) but the
Thermal analysis demonstrates that poly(methylphenylsiloxane) is thermally more stable to weight loss than poly(dimethylsiloxane). The stability decreases with increasing molecular weight and with replacement of terminal hydroxyl by trimethylsilyl groups. The principal product of thermal degradation
