Method of preparing wholly aromatic liquid crystalline polyester resin and wholly aromatic liquid crystalline polyester resin prepared by the method and wholly aromatic liquid crystalline polyester resin compound

摘要

A method for producing a wholly aromatic liquid-crystalline polyester resin and a wholly aromatic liquid-crystalline polyester resin produced by the method and a compound for the wholly aromatic liquid-crystalline polyester resin are disclosed. The disclosed method for producing a wholly aromatic liquid-crystalline polyester resin comprises the steps of: synthesizing a wholly aromatic liquid-crystalline polyester prepolymer by condensation polymerization of a monomer, decompressing the interior of the reactor containing the synthesized prepolymer at a predetermined decompression speed, /RTI
