摘要

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 1H 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, 1HNMR. 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.
