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 an organic carbonate 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.

Reduction of monomer content and stabilization of polyaziridines

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 an isocyanate scavenger wherein the excess is based on the equivalent ratio of scavenger to monomeric aziridine, an to a product obtained by this process and to a coating composition containing the product obtained by the process.
