Abstract

A rigid polymer, cellulose triacetate (CTA) dissolved in a combination of trifluoroacetic acid (TFA) and methylene chloride (MC) solution are liguid crystalline above a certain concentration. A flexible polymer, polyethylene terephthalate (PET) also dissolves in TFA/MC, but does not form liguid crystal phase. Ternary solutions, CTA/PET/TFA-MC which CTA and PET were mixed in a same solvent TFA/MC (6/4 : v/v) showed phase separation and mesophase formation.
