The invention relates to a transesterification method for continuously producing a first polycarbonate and at least one second polycarbonate simultaneously from one and the same oligocarbonate in one and the same production facility. The first polycarbonate and the at least second polycarbonate are different. The different polycarbonates can differ with respect to molecular weight, solution viscosity, degree of branching, type of monomer units, the distribution of the monomer units in the polymer chain, or other properties for example. |
