Abstract: PROBLEM TO BE SOLVED: To provide a process whereby the cycle of washing the inside of a reactor for the production of a liquid crystal polyester can be prolonged, the productivity can be therefore improved, and a high-quality polyester having excellent heat resistance can be produced. SOLUTION: This process comprises reacting a liquid-crystal-polyester-forming material containing polyester polymer pellets prepared by condensing an aromatic dicarboxylic acid with an alkylene glycol and having a logarithmic viscosity of 0.8dl/g or below and a particle diameter of 2,000μm or below. In this process, the reaction mixture is agitated so that the shear rate may be 150-1,000 (1/sec).
