Melt polycondensation of decahydronaphthalate dimethyl ester with various diols enabled the synthesis of novel polyesters containing hydrogenated naphthalene rings. Decahydronaphthalene-containing polyesters demonstrated thermal stabilities above 350 degrees C, and compression molding provided ductile, optically clear films. H-1 NMR spectroscopy confirmed transesterification, and intrinsic viscosity measurements verified high molecular weights. Differential scanning calorimetry and dynamic mechanical analysis revealed structure property relationships for glass transition temperatures (T-g) and beta-relaxations. Melt rheology examined the effect of chemical structure on flow behavior, and time-temperature superposition revealed two distinct transitions, which correlated to the Tg and chain disentanglement. Furthermore, evaluation of the fractional free volume and flow activation energies suggested a structural dependence associated with regularity along the polymer backbone.
