| titleOfInvention | A kind of preparation method of polyisoprene rubber |
| abstract | The invention provides a kind of preparation method of polyisoprene rubber, the method comprises containing isoprene, the reaction mass of rare earth catalyst and solvent is sent in reactor and is carried out polyreaction, when the transformation efficiency of isoprene reaches 70-85%, stop polyreaction, and glue polyreaction obtained condenses successively, dehydration and drying, obtain polyisoprene rubber, described rare earth catalyst contains the carboxylic acid neodymium of carbonatoms 7 to 14, aluminum alkyls, halogenide and conjugated diene, the carboxylic acid neodymium of described carbonatoms 7 to 14, aluminum alkyls, the mol ratio of halogenide and conjugated diene is 1: 5-25: 1-3: 10-50.Adopt method of the present invention, can when without the need to additionally add molecular weight regulator and without the need to changing catalyzer, obtain the polyisoprene rubber compared with high Mooney viscosity value. |
