In this process, cyclic polyimino ethers with a DELTA <2>-oxazoline or DELTA <2>5,6-dihydro-4H-1,3-oxazine structure are polymerized by heating them alone or together with cyclic monoimino ethers of the same type, or with lactones, plus cationic-polymerization catalysts. The new polymers are suitable for use as raw materials, foil materials, moulding materials and hot-setting adhesives. |
