A careful collection of monomers for biomaterial syntheses is vital for identifying and controlling the efficiency and biocompatibility of the biomaterials to become created. Synthetic polyester elastomers predicated on molecules that are endogenous to the individual metabolism have already been designed [1]. In previous studies, several investigators possess reported elastic polyesters predicated on citric acid, specifically polyoctanediol citrate (POC) [2], poly(alkenylene maleate citrate) [3], poly(xylitol-co-citrate) [4] and poly(mannitol citric dicarboxylate) [5]. Although several biodegradable elastomers have already been developed, many of them require complex and costly synthetic procedures, which result in higher production costs and hinder the industrial and clinical execution of their make use of in tissue engineering [6]. Also, as even more stringent material necessity in tissue engineering is manufactured, there exists a continuous dependence on newer components’ synthesis and design [7]. The objective of today's work is to create polyesters using citric acid, sebacic acid, itaconic acid and 1,12-dodecanediol. To synthesize the polyesters by melt condensation, thermal polyesterification technique without needing catalysts or coreagents, causeing this to be method attractive for the formation of polyesters useful in medical applications. The selected monomers are expected to supply the polyesters with physico-chemical properties that may be considerably effect the degradation and biocompatibility of the synthesized polyesters. Materials and Strategies Results and Debate Synthesis and Characterization of the polyesters The copolyesters had been synthesized by melt condensation of monomers predicated on the schematic representation in Statistics 1a and 1b. The FT-IR spectra.
