摘要：
The present invention relates to a process for preparing polycarbonate comprising copolymerizing an epoxy compound and carbon dioxide (CO2) in the presence of a catalytic system comprising:
at least one catalyst selected from complexes of a transition metal;
at least one co-catalyst selected from ionic compounds, as well as to a catalytic system comprising:
at least one catalyst selected from complexes of a transition metal;
at least one co-catalyst selected from ionic compounds.
at least one catalyst selected from complexes of a transition metal;
at least one co-catalyst selected from ionic compounds, as well as to a catalytic system comprising:
at least one catalyst selected from complexes of a transition metal;
at least one co-catalyst selected from ionic compounds.
