| titleOfInvention | Application of chromium-series metal organic framework material in olefin polymerization |
| abstract | The invention relates to an application of a chromium-based metal organic framework material in olefin polymerization, belonging to the technical field of metal organic framework material catalysis. The application is as a catalyst for catalyzing polymerization reaction of olefin polymerization and as a raw material for preparing a high-molecular composite material coated with a chromium metal organic framework material. When the catalyst is used for catalyzing olefin polymerization reaction, the polymerization activity is high, the selectivity is good, and the molecular weight of the obtained olefin polymer is high; particularly catalyzing isoprene polymerization, the selectivity of cis-1, 4-polyisoprene is as high as 95 percent, the molecular weight is as high as 188 ten thousand, the molecular weight distribution is narrow, and the dispersion coefficient can reach 1.17; the chromium-based metal organic framework material can be used as a raw material in olefin polymerization, is used for preparing a high-molecular composite material coated with the metal organic framework material, solves the problems of complex preparation process and high cost, and the prepared composite material has good thermal stability, high carbon dioxide adsorption amount, environmental protection and economy. |
