Polyarylates are important class of polyesters, which are used for different application areas to improve thermal and mechanical properties of polymeric materials. They are also known as weatherable polymers that provide enhanced UV-protection. The different monomer compositions and their ratios in the polyesters affect the physical properties of polymers, such as flexibility or rigidity of polymer chains. On the other hand, linear and symmetrical monomer units make ordered packing while non-linear and non-symmetrical monomer units may produce cyclic oligomers. Therefore, they influence the glass transition temperatures (Tg) and the melting point (Tm) of the polymers. Previous studies performed in the literature involved the syntheses of polyarylates containing a composition of 1:1 ratio of 1,3 and 1,4 disubstituted acid chlorides. In this study, it was aimed to synthesize various polyesters with different ratios of these diacid chlorides to observe the structure-property relationship of the polymers. Furthermore, the syntheses of poly(ester-anhydrides) with the same monomers were performed to investigate the effect of anhydride linkages in the polymer backbone.
