Abstract

Physical and chemical interactions and miscibility in two binary blend systems: diglycidylether of bisphenol-A (DGEBA) with poly(methyl methacrylate) (PMMA) and DGEBA with bisphenol-A polycarbonate (PC), were investigated by differential scanning calorimetry and Fourier transform infra-red (i.r.) spectroscopy. Miscibility was found to exist in both binary blend systems (DGEBA/PC and DGEBA/PMMA blends) before and after heating. Chemical exchange reactions upon heating did not occur between DGEBA and PMMA; however, chemical interactions between the DGEBA and PC components in the blends were proven by evidence of elevation of the glass transition temperatures, shifting of the carbonyl i.r. absorbance peak, and unusual solvent resistance of the blends after heat treatment. The most probable crosslinked structure in the heated DGEBA/PC blend was elucidated.
