STRUCTURE AND THERMAL-PROPERTIES OF BLENDS OF NYLON-6 AND A LIQUID-CRYSTAL COPOLYESTER

Blends of nylon 6 with the liquid crystal copolyester Vectra have been prepared from the melt with different compositions, and their thermal behaviour has been analysed by differential scanning calorimetry (d.s .c.) and Xray diffraction (WAXS) using syncrotron radiation, as a func tion of temperature and thermal treatment. The structural properties o f these blends have been found to be very sensitive to the thermal his tory, and particular attention has been paid to the effect of the liqu id crystal content in the polymorphic transformations of nylon 6.
