    • PROBLEM TO BE SOLVED: To provide a catalyst for the production of a polycarbonate, easily separable from the polycarbonate to enable repeated use and having high catalytic efficiency and provide a method for producing a polycarbonate having high quality in high efficiency by using the catalyst of the invention without using harmful chlorine gas and phosgene and halogenated organic solvents supposed to have adverse effect on the environment such as dichloromethane and chloroform.
      SOLUTION: The catalyst for the production of a polycarbonate contains (A) a reaction product of (a) a catalyst carrier, (b) a palladium compound and (c) a metallic compound having redox catalyst activity and (B) a compound produced by partly or totally quaternizing the nitrogen or phosphorus of an organic carrier or inorganic carrier with an alkyl halide. The method for the production of a polycarbonate comprises the 1st step to produce a polycarbonate prepolymer by reacting an aromatic dihydroxy compound, a monohydric phenol, carbon monoxide and oxygen using the catalyst and the 2nd step to perform the solid-phase polymerization of the polycarbonate prepolymer.
