Summary:PURPOSE: Provided is a secondary plasticizer composition based on a styrene derivative, which is added upon processing a polyvinyl chloride resin, ensures viscosity stability, avoids surface tackiness in end-products, and gives flexible PVC products free from discoloration. CONSTITUTION: The secondary plasticizer composition for a polyvinyl chloride resin comprises at least one compound selected from the styrene derivatives represented by formula 1, wherein each of R1 and R2 is the same or different and represents H or a C1-C4 alkyl group. The plasticizer composition comprises phenyl tolylethane or a mixture of phenyl tolylethane with phenylxylylethane. The plasticizer composition may further comprise N,N'-dialkylpyridinium chloride and aluminum-polyoxyethylene complex.
