The alternating copolymerization of carbon dioxide and epoxides to give polycarbonates and cyclic carbonates
has attracted the attention of researchers since it fixes CO2, a green house gas, chemically. This review
makes an attempt to present a critical assessment of the available information particularly on copolymerization of
propylene oxide and CO2 and thereby indicates the areas and gaps where further work is required. The efficacy of
various inorganic, organometallic and ligand metal complexes has been thoroughly analyzed.
Keywords: Copolymerization, CO2 sequestration, propylene oxide, poly(propylene carbonate), cyclic carbonate, catalysts.
