Abstract

Abstract:

The acetone solution casting films of poly(methylmethacrylate)under natural evaporation and ultrasonic vibration were respectively characterized by DSC(Differential Scanning Calorimetry)and PyGC-MS(Pyrolysis Gas Chromatography-Mass Spectroscopy).Analytical results indicate that the condensed structure of the polymer and the residue solvent in the films are both different in different film-forming conditions,and that the residue solvated acetone in the film prepared under natural evaporation is twelve times that under ultrasonic vibration.

Key words: solution casting, poly(methylmethacrylate), ultrasonic, condensed structure, characterization
