## Abstract Highly efficient formation of poly(propylene carbonate) can be achieved in the coupling of CO~2~ and propylene oxide assisted by 4β(__N,N__βdimethylamino)pyridine (DMAP) and catalyzed with salen chromium(III) chloride by using DMAP/Cr ratios of less than 2. Under these conditions a poss
