Novel poly(amino‐quinone)s were quantitatively prepared from in situ produced 2‐methylbenzoquinone and 2‐phenylbenzoquinone with Jeffamine D‐400 ® in the presence of calcium hypochlorite as the oxidizing agent. These polymers were readily soluble in most of the organic solvents such as ethanol, acetone, tetrahydrofuran, chloroform, N,N ‐dimethylformamide (DMF), N ‐methyl‐2‐pyrrolidone (NMP), and N,N ‐dimethylacetamide (DMAc). The coatings prepared from these polymers showed very good adhesion to metals, hardness, and flexibility even after curing at 110°C for 5 h. Particularly, coatings formulated with epoxy‐novalac resin D.E.N‐438 showed excellent corrosion resistance in artificial sea water and did not form any blisters. © 1994 John Wiley & Sons, Inc.
