Abstract
A polyalkylene carbonate, an alternating copolymer, may be prepared by the ring opening of an alkene oxide or an alkene oxide precursor in the presence of carbon dioxide or any substance delivering carbon oxide, in the presence of at least one catalyst comprising a metal-organic framework material, wherein said framework material comprises pores and a metal ion and an at least bidentate organic compound, said bidentate organic compound being coordinately bound to the metal ion.
