Abstract: The self-made rubber seed oil epoxy fatty acid methyl ester(ERSO)plasticizer and the traditional petroleum
base plasticizer dioctyl phthalate (DOP)plasticizer were mixed and used in PVC as mied plasticizers. The effects of plasticizing
were studied and the effects of substiution of ERSO for OP were also evaluated. Results show that the mixed plasticizers can
significantly mroe he proper is of flexibility, hemical resistance, eat resistance and processing theology of PVC, while the
properties of, water resistance volatile, and surface hardness are slightly decreased. On the basis of comprehensive compare, ED-20
is considered as the optimiza ion mied lasticizer fomula It is indicaed that compared with DOP, the addition of the Ed-20could
increase the elongation at break of PVC by 29.83%, increase the thermal aging time for nearly 3 times, reduce the glass transition
temperature to-1.06 C and prolong the dynamic thermal stability time by 32.59%. The substitution rate of ERSO for DOP could
reach 50%, which greatly expand the application range of environmental plasticizer
