In the present study new unsaturated terpolyesters based on diarylidenecyclohexanone, were synthesized by the interfacial polycondensation polymerization technique. Aldol condensation reaction in acid media was used for preparation of three kinds of monomers and investigated by FT IR and 1 H NMR as discussed in our resent work. The terpolymers were synthetized by the polymerization of 2,6-bis (4-hydrxybenzylidene) cyclohexanone I, 2,6-bis (3-hydroxybezylidene) cyclohexanone II, and 2,6-bis (4-hydroxy-3-methoxybenzylidene) cyclohexanone III with isophthaloyl, terphthaloyl, adipoyl, sebacoyl and azobenzene 4,4-dicaroxyldichloride. The resulting terpolyesters were characterized by FT-IR, 1 HNMR. The molecular weight was determined by the intrinsic viscosity measurements. The thermal stabilities of the prepared Terpolyester were evaluated thermogravimeteric analysis (TGA). Differential thermal analysis (DTA) was used for determination of glass temperatures. X-ray analysis shows the degree of crystallinity. The morphological properties of some selected polymers were detected by SEM.

“…It was reported that, based on X-ray diffraction analysis, various arrangement of alkyl chains in organoclays had proposed. Novel organomontmorillonites have been synthesized and characterized using different ammonium compounds [7][8]. In this study, two new different ammonium compounds 3-(4-aminophenyl)-1-(4-chlorophenyl) prop-2-en-1-on (CH) and 4-((4-nitrophenyl)diazenyl)-N-(pyrimidin-2-yl)(AZ) were used to modify the compatibility of bentonite clay.…”

Organclays (OBNTs) were prepared using two new organic surfactants including 3-(4-aminophenyl)-1-(4-chlorophenyl)prop-2-en-1-on (CH) synthesized from a Claisen-Schmidt condensation reaction between p-aminoacetophenone and p-chlorobenzaldehyde; and 4-((4-nitrophenyl)diazenyl)-N-(pyrimidin-2-yl) (AZ) prepared from reaction of sulfadiazine and p-nitoaniline. Organclays OBNTs were characterized by Fourier transform infrared spectroscopy (FTIR) to evaluate the incorporation of surfactants in bentonite. The X-ray diffraction (XRD) technique was utilized to indicate the basal spacing of the treated clay as a measure of susceptibility of new organoclays. The FTIR and XRD results showed that the OBNTs were successfully incorporated in the layers of bentonite clay. Thermogravimetric analysis (TGA) was also used to determine thermal stability. An enhancement in stability was observed in OBNTs compare to pure bentonite. OBNTs prepared in this study can be used to produce disposable packaging a promising polymer nanocomposite.

New series of unsaturated copolyesters based on diarylidenecyclohexanone, were synthesized by the interfacial polycondensation polymerization technique. Aldol condensation reaction in acid media was used for preparation of three kinds of monomers and investigated by FT IR and 1 H NMR. The copolymers have been synthetized by the polymerization of 2, 6-bis (4-hydrxybenzylidene) cyclohexanone I, 2, 6-bis (3-hydroxybezylidene) cyclohexanone II, or 2, 6-bis (4-hydroxy-3-methoxybenzylidene) cyclohexanone III with isophthaloyl, terphthaloyl, adipoyl, sebacoyl and azobenzene 4, 4-dicaroxyldichloride. The resulting copolyesters were characterized by FT-IR, 1 HNMR. The intrinsic viscosity of these copolyesters was used for the determination of the molecular weight. The thermal stabilities of the prepared copolyesters were evaluated thermogravimeteric analysis (TGA). Differential thermal analysis (DTA) was used for determination of glass temperatures. X-ray analysis showed that polymers have low degree of crystallinity. The morphological properties of some selected copolyesters were detected by SEM. The dielectric and electrical resistance, capacitance, inductance, demonstrating the insulator behaviour of copolymers.
