Abstract (en)
[origin: WO2021122286A1] The invention relates to a method for adjusting the molecular weight distribution of a polymer in a preferably predominantly irreversible polycondensation reaction and/or polyaddition reaction of the type AA+BB. The invention further relates to the polymer, which is obtained by the method according to the invention, and to the further reaction of this polymer by dosing further monomers. Moreover, the invention relates to a device for carrying out the method according to the invention.
