Abstract: Research progresses in synthesis, modification, and production of poly(propylene carbonate) (PPC) were reviewed. Market prospect of PPC was also forecasted. Main catalyst systems used for polymerization of PPC are zinc catalysts, dual metal reforming catalysts, rare earth catalysts, Salen(MX) catalysts, and metal loporphyrin-based catalysts, in which zinc catalysts possess the highest catalytic activity, binary or bifunctional Salen（MX）composites provide the highest efficiency. Among the modification methods, crosslinking, copolymerizing, solution blending, and melt blending are frequently used. In China, PPC has very capacious market prospect.

Key words: poly(propylene carbonate), catalyst, synthesis, modification, biodegradability
