Azidopyrazole as Initiator for Ethylene Carbonate Ring Opening Polymerization
2019
A green approach for ethylene carbonate ring opening polymerization was proposed via an interaction between ethylene carbonate and 5-azido-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde (azidopyrazole) in presence of FeCl3 anhydrous as initiator. Despite the high thermodynamic stability of ethylene carbonate, reducing consumption of heat and time has been obtained. The effect of the molar ratio of azidopyrazole to ethylene carbonate has been studied and the resulted products were characterized.
