Abstract
Considering the copolymeration of carbon dioxide (CO2) and alkylene oxides to synthesize aliphatic polycarbonate,we introduced the research progress of double metal cyanide (DMC) complex catalyst used in the process following the comprehensive analysis of the application of aliphatic polycarbonate. In addition,we also analyzed the catalytic effect for different kinds of active center metal combinations in different reaction systems. The Zn-Co-DMC catalyst prepared by precipitation method was used in the catalytic system. By changing the preparation method,ligands and other conditions,we can control the morphology of the catalyst,and thus improve the catalytic activity. The Zn-Fe-DMC catalyst has good activity in the ring-opening of alkylene oxides. At the same time,we also described the combinations of other active center metals for the preparation of DMC catalyst,and got the conclusion that the activity of the copolymerization of CO2 and alkylene oxide was strongly affected by the central metal and ligand. Finally,the mechanism of the copolymerization was introduced,and then we pointed out the direction for the design of the DMC catalyst.关键词
