Study on the Thermal Behaviors and the Morphology in PVP/ PA66 Blends
In this paper, PA 66 were solution blended with poly(vinyl pyrrolidone)(PVP), an amorphous polar polyamide. The thermal behaviors and morphology in the blends of polyamides (PA66)) and PVP were investigated by WAXD, DSC, FT-IR and POM methods. The equilibrium melting temperatures for PA 66 in the blends were estimated based on the linear and non-linear Hoffman-Weeks (LHW and NLHW) extrapolative methods. The interaction mode between PVP and PA66 was investigated by FT-IR spectroscopy.
