The increase in waste polymer recycling has helped promoting sustainability, and together with the use of renewable raw materials, it become a widespread concept positive effects on both economy ecology. Accordingly, aim this study was synthesis “green” plasticizers, marked as LA/PG/PET/EG/LA, formed from poly(ethylene terephthalate) (PET) bio-based platform chemicals propylene glycol (PG) levulinic acid (LA). structure obtained plasticizers complex, confirmed by results nuclear magnetic resonance (NMR) Fourier-transform infrared spectroscopy (FTIR) analysis. LA/PG/PET/EG/LA poly(vinyl chloride) (PVC) were used an optimized technology for PVC re-granulate production. hardness PVC-based material comparison to commercial plasticizer dioctyl terephthalate (DOTP), increased 11.3%, while migration decreased. An improved homogeneity wettability fibers matrix observed using SEM analysis material’s fracture surface, higher efficiency intermolecular interactions leading better mechanical performances newly designed materials. Thus, are unique materials good compounding plasticizing potential PVC, revealed differential scanning calorimetry (DSC) dynamic (DMA). In that manner, bio-renewable resources recycled polymers will contribute diminishing generation, contributing lower carbon footprint.
