For the improvement of poly (N-isopropylacrylamide) properties, new series of poly (N-isopropylacrylamide-Co-acrylic acid-Co-vanillin acrylate) terpolymer was fabricated with molar concentrations 5, 10, and 15 mol% of acrylic acid (AA) with 10 mol% of vanillin acrylate (VA). Monomer and polymers were chemically evaluated using (1H NMR, 13C, FT-IR, and UV); all structures emphasized logical results. The post-polymerization has been done for terpolymer with tryptophan and threonine; they were chemically investigated. Polymers and post-polymers have been physically characterized using SEM, X-ray, DSC, TGA, and SEM. Lower critical solution temperature was measured using turbidity by UV–VIS spectroscopy and by micro-DSC. These polymers will be used in the post-polymerization of many biomolecules for biomedical applications
