Abstract
The present invention relates to a process for chemically degrading materials containing benzoxazine resin, in particular benzoxazine resins, benzoxazine resin pre-polymers and benzoxazine resin-containing plastics, that enables a high quality recycling process for used up benzoxazine resin-containing materials, in particular the separation of composite materials, such as duromer-based fiber composite plastics containing a benzoxazine resin matrix, and reuse of the benzoxazine-containing materials.
