A mechanism for the thermal degradation of cellulose triacetate in vacuo is proposed, having as its principal features deacetylation in the polymer chain and chain-scission at the 1,4glycosidic linkages between pyranose rings. The former process results in formation of acetic acid, the latter in the

## Abstract The photooxidative degradation of acrylic fibers was investigated with two different fiber‐spinning processes, that is, dry spinning and wet spinning. Several analytical methods were used in this study: viscometry, X‐ray diffraction, Fourier transform infrared spectroscopy, optical meas
