Abstract	The thermal degradation of poly (α-methyl styrene) in several mixed solvents (toluene-n-butylalcohol, toluene-sec-butylalcohol, toluene-kerosene, toluene-methyl ethyl ketone) without hydroquinone, and in with the addition of the hydroquinone, was studied at temps. of 165°~ 205℃. The velocity constant of degradation (k), and the activation energy (E) were calculated for each solvent. As results, k decreased with the increase of the volume-fraction of poor solvent in both systems, whereas E either showed no perceptible change or it increased with the volume-fraction of poor solvents. These results were discussed.
