A unique biobased polyester poly(succinic acid-glyceryl monooleate) (PSAGMO) was synthesized andcharacterized from succinic acid (SA) and glyceryl monooleate (GMO). The polyester was characterized by gel permeationchromatography (GPC), Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic response spectroscopy(NMR). The polyester was used as the plasticizer of poly (vinyl chloride) (PVC). The mechanical propertiesand the thermodynamic properties of the blends were characterized. The TG-DTA data indicated that the thermal degradationtemperature (Td) of PVC blends plasticized with PSAGMO could increase from 249.3 oC to 255.6 oC. TheDMA showed that the glass transition temperature (Tg) of the PVC blends decreased from 49.5 oC to 35 oC. The mechanicalproperties indicated that the PSAGMO could decrease the tensile strength and increase the elongation at break ofthe PVC blends. This study may lead to the development of new type of PVC plasticizer based on renewable resource.
