Abstract

In the process described, cyclic polyimino ethers with .DELTA..sup.2 -oxazoline or .DELTA..sup.2 -5,6-dihydro-4H-1,3-oxazine structure are applied, alone or together with cyclic monoimino ethers of the same type, or with lactones, plus cationic polymerization catalysts, to solid surfaces and polymerized by heating. The process gives smooth, glossy coatings with high adhesive strength, hardness, and elasticity.
