| titleOfInvention | Catalyzing system for isoprene polymerization and preparation and application method of catalyzing system |
| abstract | The invention belongs to a catalyzing system for isoprene polymerization and preparation and an application method of the catalyzing system. The catalyzing system is composed of A) rare earth organic carboxylate compound, B) organic aluminum compound, C) activating agent, D) acrylate compound and E) carboxylic aromatic cyclic ester compound containing total carbon number of C7-C9 according to molar ratios that A:B=1:1-30, A:C=1:1-3, A:D=1:1-60, and A:E=1:5-50. The prepared catalyzing system forms pre-polymerized catalyst activity central body during ageing at 0-80 DEG C. The catalyzing system can be maintained for 180 days at the room temperature, the monomer conversion rate is higher than 98% in polymerization, the molecular weight distribution index of the synthesized poly-isoprene rubber is 1.6-2.8, cis-form 1,4 structural unit content is higher than 96%, and the Mooney viscosity satisfies that ML1+4100 DEG C =40-80. |
