AROMATIC LIQUID CRYSTAL POLYESTER FILM PREPARED BY CASTING SOLUTION COMPRISING SOLVENT CONTAINING HALOGEN-SUBSTITUTED PHENOL, AROMATIC LC POLYESTER FILM AND NON-LC RESIN ON SUPPORTER AND REMOVING THE SOLVENT, AND ITS PREPARATION METHOD

摘要

PURPOSE: Provided are an aromatic liquid crystal polyester film which is excellent in the adhesion to a supporter, and its preparation method. CONSTITUTION: The method comprises the steps of casting an aromatic liquid crystal polyester solution comprising a solvent containing a halogen-substituted phenol represented by the formula 1, 100 parts by weight of an aromatic liquid crystal polyester film and 1-200 parts by weight of a non-liquid crystal resin, on a supporter; and removing the solvent, wherein A is a halogen atom or a trihalomethyl group; i is an integer of 1-5; and if i is 2 or more, As can be identical or different one another. Preferably the non-liquid crystal resin is at least one selected from the group consisting of polyarylate, polyether imide, polycarbonate, polyphenylene ether, polysulfone, polyethylene terephthalate, polybutylene terephthalate, poly(1,4-cyclohexylenedimethylene) terephthalate and polyethylene 2,6-naphthalate.
