Amin-quinone polyurethanes containing N-alkylated amine-quinone monomers
A series of amine-quinone diol monomers, containing the 2,5-diamino-1,4-benzoquinone group, were synthesized where the alkyl group on the amine was varied from methyl to ethyl to n-propyl. Polyurethanes were prepared from these monomers by condensation polymerization in N,N-dimethylformamide solution with toluene diiscyanate and poly(tetrahydrofuran) diol (M-n = 650). These amine-quinone polyurethanes were used as binders in metal particle tape. Samples were exposed to pH 2.0 aqueous buffer and the all amine-quinone polymers were shown to be superior in their ability to protect the iron particle against corrosion, relative to the commercial binders. There was no significant difference in the ability of the three amine-quinone polymers to inhibit corrosion. Clearly the increasing the steric bulk at the nitrogen did not affect their ability to inihibit corrosion.
