Abstract:
A process for the distillation of a mixture which consists to at least 90% by weight of a cyclic N-vinylamide and which comprises a stabilizer, wherein a polyether is added to the mixture before or during distillation and a product is obtained which consists to at least 99.5% by weight of the cyclic N-vinylamide.
