Ring opening polymerization of ethylene carbonate with base as initiator

摘要

The study presents synthesis of industrially important polymer, polyethylene ether carbonate, via ring opening polymerization of ethylene carbonate using KOH as initiator at 200℃ for 7 h. The molecular weight (1200-3400) and yield (40-80%) of the polymer were determined. The structure analysis using IR and NMR techniques showed the presence of carbonate and ether linkages in the polymer.
