<p>PCT No. PCT/EP85/00027 Sec. 371 Date Sep. 9, 1985 Sec. 102(e) Date Sep. 9, 1985 PCT Filed Jan. 30, 1985 PCT Pub. No. WO85/03513 PCT Pub. Date Aug. 15, 1985.A polyfunctional reaction product having functional phenolic OH groups is made available by reacting a phenol and an alkoxylated amino-aldehyde condensation product in the presence of a solvent and of an acid catalyst. This method makes it possible to prepare a polyfunctional 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.</p> |
