✦ Synopsis
In the previous work, we introduced new polymer blends from the advanced COPNA-resin and nylon 6. 1 The morphology of the polymer blends were quite different between the B-staged state and the fully cured state. In order to investigate a phenomenon occurred in the curing process, 13 C Fourier transform-nuclear magnetic resonance (FT-NMR) spectral analysis, 15 N FT-NMR spectral analysis, and Fourier transform infrared absorptional spectral analysis were carried out on the blends in a solid state. From the spectral analyses, it was revealed that a graft reaction occurred at the interface between the advanced COPNA-resin and the nylon 6. The difference of the morphology on the fully cured polymer blends was due to the following reason. In the curing process, generated benzyl-type cations of the B-staged Advanced COPNA-Resin initially attacked and combined with nitrogen in the amino groups of the nylon 6. In the late stage of the curing process, the cations mainly attacked and combined with p electrons of the condensed aromatics.
