실험 절차
Charging was conducted at a ratio of 0.6 mol of parahydroxybenzoic acid (PHBA) per mol of 6-hydroxy-2-naphthoic acid (HNCA), 110 ppm of a catalyst in the form of antimony trioxide was added based on the number of mols of HNCA, and the mixture was reacted for 4 hours at 300° C. under reduced pressure. Strands of molten polymer were extruded from the outlet, cooled, and cut to obtain HNCA+PHBA pellets.
