摘要：

In a series of publications the authors reported on melt rheology, morphology, and mechanical properties of the poly(ethylene terephthalate)/poly(amide-6,6) blends (PET/PA). The nonoriented samples had poor interphase bonding resulting in low impact and tensile strengths. To improve these properties the ester-amide interchange reaction was carried out in solution and in melt. In the latter case a Brabender Plastograph was used in the mixing chamber or twin-screw extruder configurations with p-toluenesulfonic acid as a catalyst. The interchange reaction was followed by 400 MHz proton and **1**3C nuclear magnetic resonance spectroscopy.
