Polycarbonate (PC) can be divided into aliphatic, alicyclic, aromatic, etc.
There are many synthetic methods of polycarbonate, such as low temperature solution polycondensation method, high temperature solution polycondensation method, pyridine method, solution phosgene method, interface polycondensation method, melt transesterification method,
The good news is that the domestic scientific research team has provided new ideas for the synthesis of polycarbonate
Under the funding of the National Natural Science Foundation of China and other projects, the team of Professor Li Zhibo of Qingdao University of Science and Technology has made progress in the organic catalytic synthesis of CO₂-based polycarbonate
CO₂ is one of the most attractive C1 renewable resources
Copolymerization of CO₂ and Epoxy to CO₂-Based Polycarbonate Catalyzed by Organophosphazene/TEB
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 research 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
