Azidopyrazole as Initiator for Ethylene Carbonate Ring Opening Polymerization

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 FeCl 3 anhydrous as initiator. Despite the high thermodynamic stability of ethylene c...

Description
Summary: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 FeCl 3 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.
