摘　　要：The present paper covers the phase behavior of poly(pbenzamide)(PBA)/Nylon 6/H 2SO 4 and poly(pphenylene terephthalamide) (PPTA)/Nylon 6/H 2SO 4 systems. The transition temperatures detected by the Depolarized Light Intensity measurements were used to construct the phase diagram in which the influence of temperature was shown. The enhanced depolarized light intensity observed in the ternary system suggests that the coil polymer chains may tend to be extended and contribute to the overall anisotropy of the liquid crystal phase.The present paper covers the phase behavior of poly(pbenzamide)(PBA)/Nylon 6/H 2SO 4 and poly(pphenylene terephthalamide) (PPTA)/Nylon 6/H 2SO 4 systems.
