PURPOSE: A plasticizer composition is provided to be environment friendly as a biphthalate-based compound and to obtain a vinyl chloride resin with excellent hardness(plasticizing efficiency), thermal stability and mechanical properties. CONSTITUTION: A plasticizer composition comprises a compound represented by chemical formula 1 or chemical formula 2, which contains a 1,2,4-trioxolane ring. In chemical formula 1, R1 is C1-12 alkyl, R2 is hydrogen or C1-12 alkyl, R3 is C1-12 alkyl, and n is an integer from 1-5. In chemical formula 2, each of R4-R6 is hydrogen or C1-12 alkyl, each of R7-R9 is C1-12 alkyl, each of n1-n3 is an integer from 0-5, where at least one of n1-n3 is 1. |
