A new interesting category of polyconjugated polymer, poly(3,5‐benzylidene)isopropylpiperidone, was obtained by condensation of isopropylpiperidone with terephthalaldehyde. Copolymerization and terpolymerization with cyclopentanone and/or cyclohexanone were also carried out. The model compound was prepared by the condensation of 2 mol benzaldehyde with isopropylpiperidone; the structure was elucidated by IR, 1 H‐NMR spectra, and elemental analyses. The polymers, copolymers, and terpolymers were characterized by elemental analyses, IR, 1 H‐NMR spectra, UV and visible spectra, viscometry, and X‐ray analysis. The thermal behavior of the synthesized polymers was evaluated by TGA and DSC analyses and correlated with their structures. The morphology of terpolymer IV was examined by a scanning electron microscope. Electrical conductivities in the 10 −9 –10 −11 Ω −1 cm −1 range were observed: doping with iodine showed a small increase. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 74: 2369–2377, 1999
