摘要：The use of bio-based polymeric plasticizers could expand the application range of plasticized poly(vinyl chloride) (PVC) materials. In this study, a novel bio-based polyester plasticizer, poly(glutaric acid-glyceryl monooleate) (PGAGMO), was synthesized from glutaric acid and glyceryl monooleate via a direct esterification and polycondensation route. The polyester plasticizer was characterized by gel permeation chromatography, H-1-nuclear magnetic resonance, and Fourier-transform infrared spectroscopy. The plasticizing effect of PGAGMO on PVC was investigated. The melting behavior, thermal properties, and mechanical properties of PVC blends were studied. The results showed that the PGAGMO could improve the thermal stability and reduce the glass transition temperature of PVC blends; when phthalates were substituted by PGAGMO in PVC blends, the thermal degradation temperature of PVC blends increased from 251.1 degrees C to 262.7 degrees C, the glass transaction temperature decreased from 49.1 degrees C to 40.2 degrees C, the plasticized PVC blends demonstrated good compatibility, and the decrement of the torque and the melt viscosity of PVC blends were conducive to processing. All results demonstrated that the PGAGMO could partially substitute for phthalates as a potential plasticizer of PVC. J. VINYL ADDIT. TECHNOL., 22:514-519, 2016. (c) 2015 Society of Plastics Engineers
