This invention relates to liquid crystalline polymers (LCPs) derived from (I) hydroquinone and/or 4,4'-biphenol and/or bis(4-hydroxylphenyl) ether, (II) terephthalic acid, (III) 2,6-naphthalene dicarboxylic acid and/or 4,4'-bibenzoic acid, (IV) 4-hydroxybenzoic acid, (V) 6-hydroxy-2-naphthoic acid, and optionally (VI) an aliphatic diol in specified ratios. In addition to forming exceptionally tough films, the LCPs are useful as molding resins or for blending with other thermoplastic polymers.
