Abstract In this study, starch was modified with different amounts of boric acid, and the degree substitution synthesized compounds at temperatures times determined by Fourier transform infrared (FTIR) titration methods. The degrees in both methods showed similar tendency. Optimum conditions were determined, thermoplastic (TPS) acid (B) films prepared casting method using glycerol as plasticizer. morphological properties studied scanning electron microscope‐energy dispersive spectrometry (SEM‐EDS). According to FTIR results, it observed that BO BOC stretching vibrations increased when amount increased. tensile strength, water barrier (swelling capacity, solubility, vapor permeability), optical samples investigated. swelling permeability decreased addition 0.5% starch, but highest strength achieved. for TPSB0.5% compared control group TPS. addition, film transparency.
