Abstract: PROBLEM TO BE SOLVED: To provide a horizontal continuous condensation polymerization apparatus which enables obtaining high quality polymers by improving productivity by speeding up the reaction rate of polymerization and, simultaneously, inhibiting formation of denatured products. SOLUTION: This horizontal continuous condensation polymerization apparatus comprises a vessel 1 extending long sideways having a feed opening 2 at one end in the longitudinal direction, a polymer take-out opening 3 at the other end and a discharge opening 4 for a volatile component at its upper portion; a plurality of stirring disks 5 arranged at spaced intervals in the longitudinal direction within vessel 1; an upper space 14 having a vertical length of 8-35% of the diameter D of the stirring disks provided between the upper end of stirring disks 5 and the top portion of the inner wall of the vessel without arranging a revolving shaft at the center of rotation of stirring disks 5.
