Monomers of phathalic acid mono-(4-carboxy-phenyl) ester (AC1) and But-2-enedioic acid mono (2-carboxy-phenyl) ester (AC2) were synthesized from phathalic anhydride with p-hydroxy benzoic acid and maleic anhydride with salicylic acid, respectively. The new unsaturated polyester resins were made through condensation reaction between the dicarboxylic acid and polyols in the presence of p-Toluene sulphonic acid as catalyst. In addition, solubility of prepared unsaturated polyesters was measured and the solubility of its was good in a polar protic solvents such as DMSO, CH 2 Cl 2 , THF, DMF, acetone and some non-polar solvents such as Benzene and CH 3 Cl, while it was a little solubility in both H 2 SO 4 and HCl. The chemical structures of these monomers and new unsaturated polyesters were confirmed by FTIR, 1 HNMR. Thermal analysis of polyesters by thermo gravimetric analysis (TGA) reveals that these Aromatic polyesters possess thermal stability, differential scanning calorimetry (DSC). Carbon Nano and Nano TiO 2 reinforced polyester composites. The mechanical properties (tensile strength, elongation at break and hardness) were studied.
