Abstract (en)

[origin: DE19545874A1] The invention relates to a process for continuous production of homopolymers of ethylene imine by polymerisation of ethylene imine in a solvent in the presence of catalysts at temperatures of at least 80 DEG C in a homogenous fluid phase in a tubular reactor in which the ratio of the length to the internal diameter is at least 5. Polyethylene imines with a secondary nitrogen atom content of greater than 40 to 60 % and a molecular weight distribution Mw/Mn of 1.5 to 3 are obtained.
