Abstract A polyfunctional reaction product having func- tional phenolic OH groups is made available by reacting a phenol and an alkoxylated amine-aldehyde condensation product in the presence of a solvent and of an acid cata- lyst. This method makes it possible to prepare a poly- functional phenolic reaction product which is soluble in organic solvents at a low ratio of phenolic OH groups to alkoxy groups without gelling. The reaction product is particularly useful as a curing agent for epoxy resins.
