Abstract

Polymers (A) containing oxazine groups are prepared by reacting a polymer (T) containing nitrile groups with a monoaminoalcohol in the presence of a catalyst by a process in which the polymer T is reacted in the melt with the monoaminoalcohol in the presence of the catalyst and in the absence of a solvent.
