Abstract
The present invention provides a method for producing a liquid crystalline polyester, the method comprising the steps of reacting monomers to obtain a polycondensate corresponding thereto, granulating the polycondensate to obtain a granule, and subjecting the granule to solid-phase polymerization to obtain a liquid crystalline polyester, wherein the content of iron in the granule to be subjected to the step (C) is 5 ppm by weight or less. According to the present invention, a liquid crystalline polyester having high whiteness and excellent heat resistance can be produced with satisfactory operability.
