The invention is an improved method for the preparation of poly-amine-quinone polymers using external oxidizing agents. The polymer produced has the general chemical formula: <IMAGE> where each R is independently selected from the group of alkyl, cycloalkyl, aralkyl, aryl, silyl, siloxyl and the alkyl, alkoxy, aryl, carboxyl, amino, sulfhydryl, sulfoxyl, sulfonyl substituted derivatives thereof and n is about 50-2,000, and the molecular weight of the polymer is about 10,000 to 1,000,000, preferably about 10,000 to 40,000. The polymer can be used in anticorrosion paints and coatings, such as automotive and marine paints and coatings, and can also be used as a curing agent for epoxy resins. |
