    摘要: A potassium catalyst is used in combination with a cobalt catalyst to increase the reaction rate and/or reduce the reaction temperature of a melt polymerization process for producing an anisotropic melt-phase forming polymer derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, aromatic hydroxycarboxylic acid, aromatic diol, at least a portion of which is resorcinol and at least one aromatic dicarboxylic acid, compared to a like process wherein either catalyst is used alone.
