Abstract: A multi-chamber reactor as described in the parent Specification for the continuous manufacture of polyethylene phthalates from dimethyl phthalates and ethylene glycol, has at least two chambers, preferably the last ones, provided with an adjustable discharge device 6, 7 communicating with a processing device disposed after the reactor so that the degree of polymerization and viscosity of the product is adjustable. The discharge devices 6, 7 are variable drive screw pumps or worm pumps leading through pipes 8 and 9 which join immediately before the inlet of a mixer 10 forming part of the processing device.
