The characteristics of melting endotherm, X-ray diffraction patterns of α form PVA crystals and hydrogen-bonded hydroxyl groups originally associated with the PVA resin almost disappear after blending less than 16.7wt% of PVA in NYC resins. However, the characteristics of melting endotherm, X-ray diffraction of α form PVA crystals and hydrogen-bonded hydroxyl groups originally associated with the PVA resins appear gradually as the PVA contents of NYC/PVA specimens are more than 16.7wt%. The torques vs. time measurements and tensile properties of NYC/PVA specimens support the ideas that PVA molecules are miscible with PA molecules to some extents in the molecular level as the PVA contents of NYC/PVA specimens are less than 16.7wt%. Moreover, the additional demarcated humps and significantly increased torques and "stabilized” time values support the presence of separated PVA phases in NYC/PVA specimens as their PVA contents are more than 50wt%. On the other hand, the α form PA crystals continue to grow at the expense of γ form PA crystals as the PVA contents of NYC/PVA specimens increase, and the characteristics of the γ form PA crystals originally shown on the melting endotherm and X-ray diffraction patterns of the NYC resin can barely be seen as the PVA contents of NYC/PVA specimens are equal to or more than 50wt%. Possible reasons accounting for these interesting blending properties are proposed.
