Synthesis of new supramolecular elastomers from sunflower oil and palm acid oil

New supramolecular elastomers were synthesized using vegetable oil materials namely palm acid oil (PAO) and sunflower oil (SFO). The oils were first epoxidized by using formic acid and hydrogen peroxide. The epoxidized oils and adipic acid (AA) were then reacted to make polyacids, mainly triacid. Mo...
