Summary
In the absence of significant tranesterification, blends of poly(ethylene terephthalate) and poly(bisphenol-A carbonate) were found to be almost completely immiscible over the range of compositions studied. Although the observed behavior was sometimes erratic, poly(bisphenol-A carbonate) appears to exert a significant influence on PET melting behavior and normalized heat of fusion.
