抄録

In this paper, the miscibility of poly (ethylene-co-vinyl alcohol) (EVOH) /Nylon 6 (PA 6) blends was investigated by using differential scanning calorimetry (DSC) and dynamic mechanical measurements (DMA). Tg determined by DSC shifted after the material was annealed at 235°C and reached constant values after an annealing time of 15 min. After spontaneous cooling from Tm, a mixed amorphous phase of this system was found to be miscible, in spite of coexisting with two distinct crystalline phases. In addition, the shapes of tan δ-temperature curve originating from glass transition temperature (Tg) obtained by DMA showed a single peak. And the composition dependence of the peaks was fit the Gordon-Taylor equation. Therefore, it was suggested that poly (ethylene-co-vinyl alcohol) /Nylon 6 blends were also miscible above the melting temperature.
