In this paper the progress on synthesis, properties and application of aliphatic polycarbonated polyurethane elastomer (APC-PUE) has been reviewed. It is a novel material prepared from aliphatic polycarbonate polyols (APC), isocyanate and chain extender. And one of its materials APC has been important materials in polyurethane field for decades. Compared with routine polyether polyurethane APC-PUE possesses good mechanical strength and biocompatibility. At the same time APC-PUE has better hydrolysis resistance than polyester polyurethane elastomer. APC can be obtained by reaction of phosgene, transesterification, ring opening of cyclic carbonate or copolymerization of carbon dioxide. At present most APC was obtained by transesterification of polyol and aliphatic carbonate. Due to expensive price of APC, APC-PUE can only be applied as biomaterial in special cases. Other efficient synthesis of APC such as copolymerization of carbon dioxide and epoxides would be prospective in the near future.
