摘要：
A process for producing a liquid crystalline polymer with increased polymerization rate and reduced deposition of monomer-derived substances to the reaction vessel during production is provided. A liquid crystalline polymer having a constituent unit derived from 4-hydroxybenzoic acid in an amount 8 mol % or less is produced by conducting reaction at the presence of a catalytic amount of a catalyst comprising a potassium compound and a trivalent cobalt compound in combination.
