"SYNTHESIS, CHARACTERIZATION AND COMPARISON OF BIODEGRADABLE ALIPHATIC COPOLYESTERS: POLY ETHYLENE GLYCOL OCTANEDIOL SEBACATE AND POLYETHYLENE GLYCOL DODECANEDIOL ADIPATE"

Biodegradable random aliphatic copolymers were synthesized through melt polycondensation with titanium tetraisopropoxide Ti(ipo)4 as a catalyst to produce polyethylene glycol octanediol sebacate (PEOSEB) and polyethylene glycol dodecanediol adipate (PEDDAD).The prepared copolymers were characterized by Fourier transform vibrational spectroscopy(FTIR), Nuclear magnetic resonance (NMR), Differential scanning calorimetry (DSC), Thermo gravimetric analysis (TGA) and Wide angle x-ray diffraction studies (WAXD).The viscosity measurements were studied using ubbelholde viscometer.Both the copolymers possessed antibacterial and antifungal properties.We have also reported the antioxidant behavior of these copolymers by DPPH method and hydrolytic degradation studies by phosphate buffer method.
