Ring opening polymerization of ethylene carbonate with base as initiator

Abstract

364-366The study presents synthesis of industrially important polymer, polyethylene ether carbonate, via ring opening polymerization of ethylene carbonate using KOH as initiator at 200°C 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
