摘要：

The thermal degradation behavior and the stability of polyacrylate adhesives were evaluated by evolved gas analysis mass spectrometry (EGA-MS) and evolved gas analysis gas chromatography/mass spectrometry (EGA-GC/MS). Thermal degradation processes of two steps for adhesives I and 2 were found from EGA-MS analysis, and the evolved gases from each thermal zone were analyzed by EGA-GC/MS. The degradation products and a residual monomer caused by isobornyl acrylate of adhesive 1 were evolved from 100 degrees C to 170 degrees C. These fumes are able to cause a failure of the optical transparency of double-sided ITO (Indium tin oxide) film throughout the ITO crystallization process. The thermal degradation of adhesive 2 occurred at a higher temperature of ca. 50 degrees C compared to adhesive 1. Consequently, adhesive 2 is more thermo-stable than adhesive 1.
