Abstract
A process for reducing black specks in anisotropic melt-phase forming liquid crystal polymer which comprises the steps of subjecting a reactor in which an anisotropic melt-forming polymer was formed to successive washes of triethylene glycol, ethylene glycol and at least one water wash, draining the reactor between washes, and drying the reactor after the water wash.
