Abstract
The Biodegradable poly(ethylene succinate) (PESu) was synthesized by melt polycondensation of ethylene glycol and succinic acid. The synthesized polymer was analyzed by 1H nuclear magnetic resonance (NMR) and Fourier transform-infrared (FT-IR) spectroscopy, diffraction X-rays (DRX) and were confirmed the chemical structure with weight-average molecular weight higher than 60,000 g.mol−1. We also investigated the Biodegradation of PES by incubating the polymer with micro-organisms such as fungi (Aspergilus Niger) and bacteria (basilus subtili). The decomposition of polymer was confirmed by observed weight loss of the polymer and microbial growth around it and the changing of structure of the polymers were confirmed by IR spectral analyses after biodegradation test.
