Abstract

In this paper, we report on the synthesis of certain novel polyester elastomers namely as Poly[poly(ethylene
glycol) suberate citrate], PPEGSuC and Poly[poly(ethylene glycol) sebacate citrate], PPEGSeC, by carrying
out catalyst free polycondenstation of multifunctional non-toxic monomers: poly(ethylene glycol) (PEG), citric
acid (CA) and suberic acid (SuA)/sebacic acid (SeA). The polyesters were characterised by solubility, viscosity
measurements, IR, 1H NMR and 13C NMR spectral methods. The thermal properties were studied using
differential scanning calorimetry. The swelling behaviour of the synthesised polyesters were studied. We
demonstrate that the chemical structure, morphology, physical integrity and surface property of the synthesised
copolyesters can be controlled by simply changing the monomers. These novel polyesters exhibit versatility in
thermal properties, hydrolysis and hydrolytic degradation as determined by the chemical structure of the
polyester elastomers. The synthesised polyesters are potential elastic biomaterials for tissue engineering.
