Abstract
The unsaturated polyester resin considered at the present time a significant matrix resin for thermosetting polymer compound. The Major objective of this study was to synthesize and characterize new unsaturated polyester resins for composite applications. Four types of new monomer polyester resins were synthesized, including: phathalic acid mono-(4-carboxy-phenyl) ester (AC1), but-2-enedioic acid mono-2-carboxy-phenyl) ester (AC2), phathalic acid mono-(2-carboxy-phenyl) ester (AC3) and but-2-enedioic acid mono (2-carboxy-phenyl) ester (AC4). These monomers were synthesized from salicylic acid and phathalic anhydride, phathalic anhydride and p-hydroxybeznoic acid, maleic anhydride and p-hydroxy benzoic acid in the presence H2SO4 as catalyst. The chemical structures were confirmed by FTIR and 1HNMR spectroscopy. New unsaturated polyesters were synthesized by the condensation reaction between (ethandiol, triehanol amine and ethylene glycol) and acids (phathalic acid mono-(4-carboxy-phenyl) ester (AC1), phathalic anhydride, phathalic acid mono-(2-carboxy-phenyl) ester)(AC1) with (maleic anhydride andbut-2-enedioic acid mono (2-carboxy-phenyl) ester ) in presence p-toluene sulphonic acid as catalyst. All of these unsaturated polyesters show good solubility in common organic solvents, such as (DMSO, CH2Cl2, THF, DMF, acetone and some non-polar solvents as Benzene and CH3Cl. Thermal analysis of polyesters by thermo gravimetric analysis (TGA) reveals that these Aromatic polyesters possess thermal stability, differential scanning calorimetry (DSC)were also studied. Unsaturated polyesters supported with some Nano fillers such as carbon Nano, TiO2 Nano and TiO2 and Zinc oxide for composite applications. The results showed that the new unsaturated polyesters reinforced fillers (Carbon Nano, Nano TiO2, TiO2 and ZnO) composites exhibit high mechanical properties at20% wt. of loading filler.
