Abstract
Polyunsaturated plant oils have gained great interest as monomers to produce biodegradable polymers obtained from renewable resources due to the limited existing sources of petroleum oil and environmental issues. Among them, soybean oil is a triglyceride of saturated and poly unsaturated fatty acids which can be polymerized via autoxidation by exposure to atmospheric oxygen at room temperature. Precious metals can catalyze the autoxidation process of unsaturated oils increasing the molecular weight with peroxide linkages in order to obtain soya oil polymer. The polymeric oil was fractionated by the extraction from the solvent-non-solvent mixture CHCl3/petroleum ether with the volume ratio of 5:15. Three polymeric oils fractions with different molecular weight (ca. 1000, 4000, and 40,000 g/mol) were obtained. Surface plasmon resonance and fluorescence emission of the nanocomposite solutions were observed. Transmission electron microscopy was used to determine size and shape of the metal nano particles. This macro peroxide initiator containing metal nanoparticles was used in free radical polymerization of some vinyl monomers in order to obtain olefin polymers containing metal nano particles. The detailed characterization of the composite materials was performed by NMR, FTIR, GPC, DSC and other physicochemical characterization methods.
