Abstract

Abstract: The present paper covers the phase behavior of poly(p-benzamide)(PBA)/Nylon 6/H₂SO₄ and poly(p-phenylene terephthalamide) (PPTA)/Nylon 6/H₂SO₄ 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.

Key words: Phase diagram, Phase transition, Liquid crystal polymer
