✦ Synopsis

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.

## Abstract A series of anion exchange membranes with pyridinium groups were prepared by aminating 100% bromomethylated poly(2,6‐dimethyl‐1,4‐phenylene oxide) with 4‐vinylpyridine. These membranes exhibited higher ion exchange capacity, lower water uptake, lower area resistance, and better thermal
