The chemical structures of copolymers formed in the transesterification of polycarbonate/poly(ethylene terephthalate) blends during melt processing were deduced from the 1H n.m.r, spectra of reaction products which were extracted in CH2C12 solvent (extracted soluble and insoluble products). The changes in the extent of reaction with the reaction conditions (reaction time, temperature and blend composition) were also interpreted by the changes of peak intensity of typical peaks in 1H n.m.r, spectra.
