Abstract
In a method for the continuous manufacture of polymers by means of melt condensation of a monomer in each case with itself or with at least one other monomer the molten monomers are esterified or transesterified in the presence of a catalyst, subsequently the esterification/transesterification product is fed for the precondensation to a disc ring reactor, then the precondensation product is fed to an LVS disc ring reactor for the polycondensation and finally the polycondensation product is fed to the end polycondensation.
