For the semi-continuous production polyadducts of alkylene oxide by an addition reaction of alkylene oxide on a chain initiator having at least one active hydrogen, there is provided a reactor (1) constituted by a cylindrical body with two diameters, the upper part being of larger diameter than the lower part, heat-exchange means (2) and recycling ducts (13, 15) for the recycling of the reaction mixture from the bottom to the head of the reactor in order to obtain the final desired product, thereby enabling the production to be carried out with greater flexibility and reduced down times.
