摘要： A process for the production of polyester comprising at least 80% of an ethylene terephthalate repeating unit using as a starting material an ester compound made mainly of terephthalic acid and ethylene glycol or an oligomer thereof is disclosed. This process is characterized in that a prepolymer having an intrinsic viscosity of not more than 0.4 dl/g and a carboxyl terminal group concentration [COOH] of not more than 90 x [η] -0.4 µeq/g is fed to a final polymerization unit and polymerized in the form of a molten thin film having a thickness of from 0.005 to 0.15 mm.

摘要： A process for the production of polyester is disclosed, comprising feeding an ester compound made mainly of terephthalic acid and ethylene glycol or an oligomer thereof to a final polymerization reactor, and then polymerizing it in the form of fine molten particles in an inert gas stream, wherein the ester compound has an intrinsic viscosity [η] of not more than 0.4 dl/g and a carboxyl terminal group concentration [COOH] of not more than 90 x [η] -0.4 µeq/g and the fine particles have an average particle diameter of from 0.015 to 0.5 mm.
