【摘要】 |
|
Acetone solution-casting films of poly(methylmethacrylate) were analyzed by differential scanning calorimetry and pyrolysis gas chromatography-mass spectroscopy under natural evaporation and ultrasonic vibration, respectively. Analytical results indicate that both the condensed structure of the polymer and the residue solvent in the films vary in different film-forming conditions and that the residue-solvated acetone in films prepared under natural evaporation is 12 times greater than that under ultrasonic vibration. |
