Abstract Herein, epoxidized soybean oil methyl ester (ESOM) plasticizer was
synthesized for the preparation of plasticized poly(vinyl chloride) (PVC) films
by the alcoholysis and epoxidation. The chemical structure of ESOM was investigated by infrared spectrum and 1H nuclear magnetic resonance. The effect of
content of ESOM and petroleum based plasticizer di-2-ethylhexyl phthalate
(DEHP) on the performance of plasticized PVC films was studied. The result
showed that substituting DEHP with ESOM can improve the thermal stability
of plasticized PVC films. When the weight ratio of ESOM and PVC is fixed at
1:2, plasticized PVC film presents higher elongation at break (350.8% vs.… More >
