Abstract

The physical and chemical interactions existing between the two blend components, tetraglycidyl-4,4′-diaminodiphenylmethane (TGDDM) and Bisphenol A polycarbonate (PC), were investigated by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The homogeneous phase behavior, which was found to exist not only in the heated binary blends of TGDDM/PC with no curing agents but also in amine-cured blends, is believed to be a result of these special chemical links developed between the TGDDM epoxy and linear PC polymer molecules. Mechanisms of chemical reactions and the resulting links between these two components upon heating of the TGDDM/PC blends (in the absence of any curing agents) have been proposed and proven by experimental results.
