چکیده انگلیسی
Five novel terepolymers based on methyl-cyclohexanone in the polymer main chain have successfully been synthesized via solution polycondensation technique. These terepolymers were prepared from the polycondensation of terephthalaldehyde with methyl-cyclohexanone and different cycloalkanone derivatives. They were characterized by viscosimetry, FT-IR, X-ray, thermal gravimetric analysis, and differential scanning calorimetry, UV-visible spectroscopy, SEM and electrical conductivities. X-ray analysis showed that it has some degree of crystallinity in the region 2θ = 5-60°. The UV-visible spectra of some selected terepolymers were measured in DMF solution and showed absorption bands in the range 272-394 nm, due to n-Ïâ and Ï-Ïâ transition. The electrical conductivities in the 10â9-10â8 Ωâ1 cmâ1 range were observed after doping with iodine.
