    Plasticized poly(vinyl chloride) (PVC) is widely used in industrial products because of its low price and various mechanical properties. The mechanical properties of PVC can be easily altered by adding plasticizers, changing rigid PVC into flexible PVC. However, growing concerns about the migration of phthalate-derived plasticizers, which can act as endocrine disruptors, have led to extensive research into alternative materials. In this work, plasticized PVC was prepared using acetylated citrate plasticizers and their potential to replace commercial phthalate derived plasticizers was investigated. Plasticized PVC was prepared by melt compounding the premixed plastisol using a twin-screw extruder. The compatibility of acetylated citrate plasticizers with PVC was compared with different commercial plasticizers by means of rheology and spectroscopy. The thermal stability and plasticizing ability of citrate plasticizers were evaluated using thermogravimetric analysis (TGA) and tensile modulus analysis, respectively. Acetylated citrates showed promising thermal and mechanical properties, making them a possible alternative to phthalate plasticizers.
