PCT No. PCT/EP90/01141 Sec. 371 Date Jan. 21, 1992 Sec. 102(e) Date Jan. 21, 1992 PCT Filed Jul. 12, 1990 PCT Pub. No. WO91/01344 PCT Pub. Date Feb. 7, 1991.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, molding materials and hot-setting adhesives.
