Recently, Li Zhibo's team developed new phosphazene catalysts: 2,4,6-tris[tris(dimethylamino)iminophosphine]-1,3,5-triazine (C3N3-Me-P3) and 2,4 ,6-Tris[tris(1-pyrrolidinyl)iminophosphine]-1,3,5-triazine (C3N3-Py-P3), and used for controlled alternating copolymerization of anhydrides and epoxides
This study enriches the organic catalytic system of CO2 and epoxy copolymerization, especially the synthesis of CO2-based polycarbonate under normal temperature and pressure conditions, which provides a new idea for the efficient conversion of CO2
