Abstract
Methods of forming low molecular weight oligomers of aniline-based compounds are provided as well as methods of forming varied molecular weight oligomers and polymers that are aniline-based which are end-functionalized and capable of being reacted with other monomeric species to form a variety of copolymers. The oligomers, end-functionalized oligomers and copolymers exhibit corrosion-resistant properties and provide corrosion-resistant compounds for use on various substrates.
