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.

A composition of phosphaphenanthrene groups-containing castor-oil-based phosphate plasticizer (PGPP) was synthesized and characterized. Flame retardant PVC blends cooperated with different mass of PGPP were prepared. Flame retardancy of PVC blends were investigated with LOI, TGA, TGA-FTIR, TGA-MS and cone calorimeter. Flame retardant mechanism was also studied. The flame retardant performance of PGPP provides novel route for efficient use of vegetable oil and preparing advanced flame retardant PVC materials.

Epoxidized castor oil (ECO) and castor oil phosphate ester (COPE) were synthesized. Structure of twofunctionalized castor oil was characterized with FTIR and 1H NMR. Property of poly (vinyl chloride) PVCblends plasticized with ECO and (COPE) as secondary plasticizer was studied. The results indicated thatthermal stability of plasticized PVC blends was improved, LOI value of PVC blends cooperated with COPEcould reach 27.8%, flame retardant performance of COPE was put into effect by promoting polymercarbonization and forming a consolidated and thick flame retardant coating, which is effective toprohibit the heat flux and air incursion.
