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 ofo-PTF was estimated using gel permeation chromatography (GPC). The cross linked biopolyesters were prepared by treatingo-PTF of olive withN-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.

In the structure of the title compound, [KPt(C6H4N3O)Cl2(C6H5N3O)(C12H24O6)], the PtII atom is in a distorted square-planar geometry. The crystal structure is consolidated by O—H⋯O hydrogen bonds. The measured crystal was a non-merohedral twin with four components.

In the title compound, C16H17N3O, the benzotriazole ring forms a dihedral angle of 77.25 (6)° with the phenyl ring. The benzotriazole ring is essentially planar with a maximum deviation of 0.012 (19) Å. Weak intermolecular C—H⋯O hydrogen bonds form R 2 2(10) motifs. The crystal packing is consolidated by π—π interactions with centroid–centroid distances of 3.5994 (12) Å together with very weak C—H⋯π interactions.
