Process for treating film comprising liquid crystal polymer

摘要

A process for treating a film comprising a liquid crystal polymer capable of forming an optically anisotropic melt phase, which comprises passing the film between press rolls at a temperature in a range of from 80 DEG C. below the melting point of the liquid crystal polymer to 5 DEG C. below the same melting point and under a linear pressure of 20 to 400 kg/cm.
