METHOD FOR PRODUCING LIQUID CRYSTAL POLYESTER COMPOSITION

摘要

The present invention provides a method for producing a liquid crystal polyester composition, the method comprising feeding a liquid crystal polyester and a polyhydric alcohol fatty acid ester into an extruder having a vent portion, followed by melt-kneading in a state where the degree of decompression of the vent portion is −0.06 MPa or less in terms of a gauge pressure. The composition obtained by the method can provide a molded article having a thin wall portion and complicated shape.
