Recently, as interest in environmental issues is increased, interest in ultraviolet rays is increasing gradually. In this study, acrylic cyanate-based products are synthesized environmental friendly UVA by improving quality and yield. Various substituents including electron donating substituents versus electron withdrawing substituents, methyl and phenyl groups were compared. This led to the introduction of methoxy substituents for comparison and analysis as the most potential substances in terms of physical properties and ecomonics. Due to this, methoxy substituent was introduced for comparison and analysis as the most potential material in terms of physical properties and economics. The process conditions (temperature, catalyst, solvent) of each synthesis method were changed to optimize the process to obtain high yields. As a results P-E was achieved UV absorbance of 88.5% in 337nm, color of solution of 66.1% in 460nm and 98.2% in 500nm, and heat stability of 25%. |
