Abstract: CO2, propylene oxide (PO), and tolylene diisocyanate (TDI) were catalytically terpoly-merized to form a polycarbonate-polyurethane (PCPU).The addition of TDI resulted inchain extending, branching and crosslinking.The terpolymer was thermally more stablethan the copolymer of CO2 and propylene oxide.

Key words: carbon dioxide, Propylene oxide, tolylene diisocyanate, terpolymerization, coordination catalyst
