| titleOfInvention | The homogeneous rare earth catalyst of neodymium series, its preparation method and application thereof |
| abstract | The present invention relates to a kind of novel homogeneous neodymium series rare earth catalyst, its preparation method and the application in conjugate diene polymerization thereof.The advantages such as having of this catalyst is homogeneous, good stability, high activity and high directionality, at the temperature more than room temperature, the cis-selective of catalyst is more than 99%.The catalyst of the present invention is especially suitable for preparation superelevation cis polybutadiene, and prepared polybutadiene cis-structure content is more than 99%, and vinyl structure content is only about 0.3%, and the cis-structure of high level can give the performance that polybutadiene is excellent.The Mooney viscosity of polybutadiene prepared by the present invention, more than about 40 or higher, meets application request. |
