Synthesis of Sunflower Oil Based Elastomer and Its Characterization by Using Spectroscopic Techniques

Summary A new elastomer was successfully materialized from sunflower oil (a vegetable oil). The reaction was confirmed by Fourier Transform Infrared (FTIR) and Fourier Transform Nuclear Magnetic Resonance (FTNMR) methods. FTIR analysis indicated that amine functional groups appear at 3325 cm−1 representing N-H stretching of primary and secondary amines and at 1645 cm−1 representing N-H deformation of primary amines. The hydrogen bonding was confirmed with the appearance a broad peak in the region 2500–3800 cm−1. FTNMR analysis also show the appearance amine functional groups at peak 5.4 ppm in 1H NMR representing proton in amine functional groups and peaks at 151 ppm and 156.6 ppm in 13C NMR representing carbon in amine functional groups.
