Abstract: The production method for a polycondensation resin of the present invention comprises the processes of: producing a low-order condensate by means of a polycondensation reaction; discharging the low-order condensate outside the system; and producing a polycondensation resin by subjecting the discharged low-order condensate to polymerisation. Here, the polycondensation reaction and the polymerisation are carried out in a batch type reaction vessel, and, in the process of discharging the low-order condensate outside the system, the low-order condensate is discharged outside the system while by-products produced in the polycondensation reaction or substances of the same kind as the raw materials of the polycondensation reaction are supplemented into the system. The production method makes it possible to produce a polycondensation resin of stable quality, in a batch type polymerisation method.
