| titleOfInvention | A kind of rare-earth catalysis system and preparation method thereof and poly-pentadiene preparation method |
| abstract | The invention provides a kind of rare-earth catalysis system, including rare earth oxide coordination compound and alkyl aluminum compound；Described rare earth oxide coordination chemistry consists of Ln 2 O 3 ·xR·yL；Wherein Ln is rare earth element；R is acid compound；L is to electron donor ligand compound；0 < x≤4；0≤y≤3.Compared with prior art, the present invention, without rare earth oxide being made rare earth carboxylate and not needing to add chloride as catalyst use, uses as catalyst without rare earth oxide is made rare earth chloride by complicated technology.Rare-earth catalysis system preparation process provided by the invention is simple, easy and simple to handle, requires relatively low to reaction condition.In addition rare-earth catalysis system raw material provided by the invention is easy to get, and the process that catalysis pentadiene monomer generation polyreaction obtains poly-pentadiene is gentle, steady, has good application prospect. |
