ABSTRACT:
The present invention relates to a process for preparing polyarylate, and more specifically, to a process for preparing polyarylate by interfacial polymerization of a bivalent phenol compound and an aromatic dicarboxylic acid or a halide thereof, which comprises mixing a cationic catalyst for the phase transition and a nonionic surfactant in a predetermined ratio, to further increase the yield of polyarylate, as compared with the case of using each of the nonionic surfactant and the cationic catalyst for the phase transition alone.
