Abstract

The invention discloses an organic molybdenum complex compound; organic ligand containing nitrogen group elements can be adopted to be matched with molybdenum to form metal organic compound, wherein the organic ligand includes triphenyl phosphine or alkyl-substituted derivative of the triphenyl phosphine, triphenyl phosphine oxide or alkyl-substituted derivative of the triphenyl phosphine oxide, triphenyl amine or alkyl-substituted derivative of the triphenyl amine, triphenyl amine oxide or alkyl-substituted derivative of the triphenyl amine oxide, triphenyl arsine or alkyl-substituted derivative of the triphenyl arsine, and triphenyl arsine oxide or alkyl-substituted derivative of the triphenyl arsine oxide. Meanwhile, the invention further discloses a preparation method of the organic molybdenum complex compound and the application of taking the organic molybdenum complex compound as catalyst in synthesizing poly-dicyclo-pentadiene. The organic molybdenum complex compound has higherchemical stability, is not sensitive for air and water vapor, can be taken as the catalyst to be applied in synthesizing the poly-dicyclo-pentadiene with higher catalytic activity, reduces the reaction conditions required by synthesizing the poly-dicyclo-pentadiene due to the chemical stability, and has good popularization and application prospects.

Description

technical field [0001] The present invention relates to a kind of metal organic compound, especially a kind of organic molybdenum complex, relate to a kind of preparation method of this organic molybdenum complex at the same time, also relate to a kind of this organic molybdenum complex in synthesizing polydicyclopentadiene in the application. Background technique [0002] Dicyclopentadiene (DCPD) can be polymerized by ring-opening metathesis to obtain a cross-linked thermosetting polydicyclopentadiene (PDCPD) plastic. The plastic has good heat resistance, creep resistance, dimensional stability, corrosion resistance and other properties. The production of PDCPD adopts the reaction injection molding (RIM) process, which has the advantages of fast molding speed, low processing temperature, and low injection pressure. It can be used to manufacture various thin-walled large parts with high performance and complex shapes, such as transportation. Automobile bumpers, guard plate...
