Polyetherols containing s-triazine rings can be obtained in reactions of oxiranes with melamine derivatives. A report on the attempt to replace pentakis(methoxymethyl)melamine with bis(methoxymethyl)melamine in the synthesis is presented. The replacement simplified the procedure by eliminating the s
