Novel cross linked biopolyesters were synthesised from naturally available olive oil, oligomeric polytriglyceride fumarate (o-PTF) was prepared by glycerolysis of the olive oil followed by condensation with maleic anhydride. The (o-PTF) was characterised by spectral (FTIR, UV, NMR) and physicochemical properties (specific gravity, viscosity, saponification value, iodine value). The molecular weight of o-PTF was estimated using gel permeation chromatography (GPC). The cross linked biopolyesters were prepared by treating o-PTF of olive with N-vinyl-2-pyrrolidone and vinyl acetate. The cross linked biopolyesters were evaluated for spectral properties (FT IR), cross linked density, thermal properties, mechanical properties and biodegradation. The potential antifungal and anti bacterial activities of the newly prepared biopolyesters were evaluated. The environment degradation was assessed by soil burial test. The outcome of the studies has revealed that the newly prepared cross linked biopolyesters are potential biodegradable material for various consumer application like package materials and agricultural applications.
