Abstract

In this study, an antibacterial polymer was successfully synthesized by copolymerization using poly(vinyl chloride) (PVC) and 2,2’,6,6’-tetra-tert-butyl-4,4’-dihydroxybiphenyl (BP-264). Covalent incorporation was supported by Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy (appearance of a BP-264 absorption band near 295 nm in PVC–BP-264), and 1H/13C nuclear magnetic resonance (NMR) spectra with corrected chemical-shift assignments for tert-butyl, aromatic, and phenolic signals. GPC showed a modest change in molecular-weight distribution after modification (Mn 4.60×104 g mol-1, Mw 9.40×104 g mol-1). Mechanical testing demonstrated improved ductility while maintaining strength: PVC–BP-264 reached a tensile strength of about 19 MPa and elongation at break of about 270%, accompanied by a slight decrease in modulus to about 1.9 GPa. Preliminary antibacterial screening by agar disk diffusion against Escherichia coli and Staphylococcus aureus revealed clear growth-inhibition zones for PVC–BP-264 compared with PVC. Overall, this study provides a chemistry-driven route to antibacterial PVC with a favorable balance of mechanical performance.
