摘要： A novel wholly aromatic polyester capable of forming an anisotropic melt phase is provided. Such polyester has been demonstrated to be capable of forming quality molded articles having a combination of excellent heat resistance and mechanical properties. The resulting polyester further is capable of readily being melt processed while using conventional equipment. Four essential recurring units are present in the polyester of the present invention wherein (I) is derived from 2,6-napthalenedicarboxylic acid and/or 4,4'-biphenyldicarboxylicacid; (II) is derived from another dicarboxylic acid (as defined) such as terephthalic acid; and (III) is derived from aromatic diols (as defined) such as 1,4-dihydroxybenzene and 4,4'-dihydroxybiphenyl; and (IV) is derived from another aromatic diol (as defined), such as 4,4'-dihydroxydiphenyl ether. In a preferred embodiment, an inorganic filler is dispersed therein. Molded articles exhibiting highly satisfactory tensile strengths, tensile elongations, and tensile moduli are made possible when melt processing the wholly aromatic polyester.
