The invention relates to a process for reducing the monomeric aziridine content
in a polyaziridine forming reaction mixture by adding to the polyaziridine forming
reaction mixture an excess of a carbodiimide scavenger wherein the excess is based
on the equivalent ratio of scavenger to monomeric aziridine, and to a product obtained
by this process and to a coating composition containing the product obtained by
the process.
