| titleOfInvention | Recyclable nitrogen-containing polycarbonate plastic synthesis method |
| abstract | The invention provides a recyclable nitrogen-containing polycarbonate plastic synthesis method, wherein a catalytic system consisting of a binuclear cobalt complex based on biphenyl and quaternary ammonium salt is used for realizing the alternating copolymerization reaction of nitrogen-containing alkylene oxide and carbon dioxide. The nitrogen-containing alkylene oxide is a biomass monomer prepared by taking furfural as a raw material, and then different carbamate structures are introduced on a ring, so that the degradation selectivity, crystallinity, thermodynamic stability and the like of a polymer can be obviously influenced due to different functional groups FG. At the same time, the nontoxic, harmless and biodegradable CO is obtained 2 The polycarbonate can be chemically degraded under the heated condition, so that the cycle from polycarbonate to alkylene oxide is realized, and the polycarbonate plastic is a novel polycarbonate plastic capable of realizing the plastic-to-monomer technology. |
