Abstract In response to the health and environmental concerns associated with plasticizer dioctyl phthalate (DOP), this research explores utilization of methyl oleate (MO) derived from plant oil, 1,2,4‐Benzeneticarboxylic anhydride (TMA) isobutyric (IA) as a precursor for synthesizing hyperbranched polyester named IA‐MO‐TMA. This serves an alternative Polyvinyl chloride (PVC). The chemical structure IA‐MO‐TMA was thoroughly characterized using Fourier Transform Infrared Spectrometer (FTIR) nuclear magnetic resonance hydrogen spectra, its molecular weight assessed. PVC film, plasticized IA‐MO‐TMA, underwent comprehensive testing techniques such differential scanning calorimetry, electron microscopy, thermogravimetric analysis. Notably, glass transition temperature ( T g ) film exhibited significant reduction 75°C −6.7°C. demonstrated elongation at break 318.1%, tensile strength 19.2 MPa, plasticizing efficiency 109.9%. Moreover, use increased initial decomposition 235.6 264.1°C. Additionally, extraction rate in petroleum ether found be 35.6% lower than that DOP.
