| Abstract: | Electron spectroscopy for chemical analysis (ESCA) and Fourier-transform infrared (FT-IR) attenuated total reflection (ATR) studies have been made on the film of blend polymers consisting of poly(hydroxypropyl ether) of bisphenol A (P) and poly(ethylene oxide) (E) or P and poly(ethylene adipate) (A) formed on nylon-6 (Ny) substrate to investigate the boundary-phase structure between the substrate and the polymer blends. For the case of P/A blend, A is enriched to the depths probed by both ESCA (below ca. 60 Å) and FT-IR-ATR (below ca. 0.7 μm) from the nylon-6 surface. For the P/E blend, though P is enriched to the depth probed by ESCA from the Ny surface, the enrichment of neither of the blend components can be found to the depth probed by FT-IR-ATR. These results indicate the different susceptibility between P/A and P/E blends to the influence from the Ny substrate. |
