    • The present invention provides: a production process that enables to keep foaming state within a constant level and to obtain a polymer with good productivity and reproducibility with a practical plant by defining an appropriate vapor velocity from a weight-average molecular weight of the polymer that is finally intended to obtain; and a polymerization apparatus therefor. A production apparatus for producing a polymer, which comprises a reactor 1 in order to produce the polymer, a stirrer 2 in order to stir a reaction solution in the reactor 1, and a condenser 3 so that a vaporized reaction solution can be cooled and returned to the reactor 1, and further comprises a vapor velocity measuring means of monitoring a vapor velocity in the condenser, and an vapor velocity adjusting means of adjusting the vapor velocity, is used. Then, the vapor velocity is adjusted in the range of 0.001 to 0.05 m/s so that a common logarithm value of a weight-average molecular weight of the polymer that is finally intended to obtain multiplied by the value of the vapor velocity can be not more than 0.15 for not less than 10% of the whole reaction time.
