abstract={A branched polyesters was synthesized using ethylene glycol, adipic acid and glycerol. It was characterized by FTIR, <SUP>1</SUP>H and <SUP>13</SUP>C-NMR, GPC, TGA/DTA. According to TGA analysis it was found that the mass loss is accomplished in two stages, the lower one was slightly distinguished in TGA. The Flynn-Ozawa-Wall method was applied for the principal reaction and the activation energies for all values of ¦Á were determined. The biodegradation process was also investigated in liquid culture media using two strains of <i>Penicillium sp </i>S1<i> </i>and <i>Aspergillus sp </i>S2 which were isolated from the discharge of Oujda city (Morocco). According to the growth curves, it was found that the <i>Penicillium sp </i>S1 and <i>Aspergillus sp </i>S2<i> </i>used the polyester as source of carbon<i>. </i>We have noted using FTIR spectra a decrease of the band intensity at ¦Ä =1170 cm<SUP>-1 </SUP>characteristic of the stretching vibration of C¨CO¨CC and also a decrease of the ester band group. The results obtained were compared with those of polyesters biodegradation reported in our previous work [27,28,29]. We have also proposed an enzyme degradation mechanism and hypothesis for an empirical mathematical formula giving the relationship between the thermal degradation and the biodegradation rate constant of the polyester.},
