The industrial LCP production process is comprised of acetylation of a monomer (hydroxybenzoic acid etc.) with acetic anhydride (Formula 1) and polycondensation by acetic acid removal (Formula 2). In the acetylation process, removing acetic acid produced as a by-product from the system causes the equilibrium to shift to the right side of Formula 1 to complete the reaction. In the polycondensation process, high molecular weight can be obtained by condensing the product of the acetylation reaction under higher temperature conditions and removing acetic acid produced as a by-product from the system as is the case with the acetylation process.
