Abstract

Phase separation have been measured at the temperature of 25 , 45 and 65 for the polymer (agar) + solvent (DMSO) + no solvent (ethanol) ternary system by using a titration method. Through combining experimental data and empirical equations, ternary phase diagram was drawn to illustrate the mechanism of spinning. Low temperature was beneficial to produce fibers and instead of ethyl alcohol with water as coagulation bath is feasible, which were shown clearly in the ternary phase diagrams.
