Bis(2,4‐diphenylbutyl) phathalate, a plasticizer for poly(vinyl chloride) (PVC), was synthesized from 2,4‐diphenyl‐1‐butene obtained by a thermal decomposition under reduced pressure of waster polystyrene. The heat stability of bis(2,4‐diphenylbutyl) phthalate was determined by thermogravimetric analysis and compared with typical plasticizers. It was recognized that bis(2,4‐diphenylbutyl) phthalate showed high heat resistant. A test sheet of plasticized PVC with bis(2,4‐diphenylbutyl) phthalate and bis(2‐ethylhexyl) phthalate was prepared. The test sheet was used for determination of the plasticizing performance of bis(2,4‐diphenylbutyl) phthalate. Although the effect of bis(2,4‐diphenylbutyl) phthalate imparting flexibility to PVC is poorer than that of bis(2‐ethylehexyl) phthalate, the former phthalate is well compatible with PVC and exceedingly heat‐resistant.
