Beschreibung
Zusammenfassung:	The invention relates to a reactor for the degassing of a polymer melt and for polycondensation, comprising a horizontally oriented reactor housing. The reactor housing has two end walls, at least one outlet for the degassed polymer melt, and at least one exhaust vapor port. The reactor of the invention is characterized in that, in the interior of the reactor housing, there is a horizontally arranged compartmenting element, which contains a rotor. The rotor has at least one opening toward an end wall of the reactor housing, which opening is delimited by a dam arrangement. Furthermore, the rotor has a rotor wall, which is impermeable to the polymer melt, and divides the interior of the reactor housing into an inner reactor compartment and an outer reactor compartment. In addition, the reactor according to the invention has a tube for supplying the polymer melt, which tube runs through the inlet-side end wall. Said tube ends in the interior of the rotor such that the polymer melt is introduced into the inner reactor compartment.
