Quinone–amine polymers. II. 1,3‐bis(3‐aminophenoxy) benzene‐p‐benzoquinone oligomers

A novel oligomeric compound has been synthesized by reacting 1,3 bis‐(3‐aminophenoxy)‐benzene (APB) with p ‐benzoquinone. A dark reddish brown product has been characterized using UV, IR, and NMR spectra, and elemental analysis. It, too, adheres to metals, as does another polyetheramine‐ p ‐benzoquinone polymer synthesized in Part I [ Prog. Org. Coating , 15 , 63 (1987)], and becomes nonwettable after heat curing. However, its moisture adsorption is only 0.1% by weight, as against 3% for the latter product. This makes it a likely candidate for insulating electronic components from moisture.
