摘要：

The reactions taking place during melt mixing of polyarylate (a copolyester of bisphenol A and an equimolar mixture of isophthalic and terephthalic acids) with poly(butylene terephthalate) (PBT) were studied by H-1 and C-13 nuclear magnetic resonance (n.m.r.). Model compounds whose structures match those of the polymers and possible interchange units were synthesized and characterized by H-1 and C-13 n.m.r. By means of this characterization, assignments of the absorptions appearing in the spectra of the soluble fraction were possible.
