ABSTRACT OF THE DISCLOSURE Novel aromatic imine polymers containing as at least a part of its entire recurring units an aromatic imino group Image wherein ? is an aromatic ring group having a valence of at least two and has at least one electron-attracting group with respect to the group Image , and R1 is a hydrogen atom or a non-aromatic hydrocarbon residue having a valence of at least 1. These polymers find a variety of applications by utilizing their thermal stability and various other desirable properties such as reducibility or photosensitivity. The polymers are prepared by reacting specific aromatic dihalogen compound with specific difunctional amino-containing compounds in an inert organic solvent in the presence of an acid acceptor. Copolymers can be obtained by carrying out the reaction using specific difunctional comonomers. - 1 -
