The liquid-phase polymerization is commonly used in the final stage of polymerization from low molecular weight prepolymer (e.g., degree of polymerization (D[P.sub.n]) = 20-30, carboxyl end group concentration ([COOH]) = 60-80 mmol/kg) to produce conventional PET (e.g., D[P.sub.n] = 100, carboxyl end group concentration ([COOH]) = 20-35 mmol/kg).
