    摘要： The invention is related to a novel compound represented by NdHA4 wherein A is a carboxylate, and to a diene polymerization catalyst using the novel compound. NdHA4 has monomeric structure and does not contain water, bases and salts. NdHA4 is mixed with a halogen compound and an organic metal compound to prepare a catalyst system. The catalyst system in the polymerization of 1,3-butadiene (BD) or isoprene produces high cis polydiene with a high activity (100 g BD/4.0×10−5 mole Nd) and without gel formation. The polydiene thus obtained is useful for tires and golf balls and as a polystyrene modifier.

    摘要： The present invention relates to a method for preparing a high 1,4-cis polybutadiene having a controlled cold flow and, more particularly, to a novel method for preparing a high 1,4-cis polybutadiene having a controlled cold flow that involves initiating polymerization of a 1,3-butadiene in the presence of a non-polar solvent using, as a polymerization catalyst, a complex prepared by mixing a neodymium compound with or without a conjugated diene compound, a halogenated organoaluminum compound or a halogenated organic compound, and an organoaluminum compound irrespective of the addition order of the catalyst; and adding an organoborane compound as a cold flow controller of 1,4-cis polybutadiene after a predetermined time of the polymerization. Accordingly, a high 1,4-cis polybutadiene having an efficiently controlled cold flow can be prepared without causing a significant increase in the Mooney viscosity (molecular weight), an odor (bad smell), and a reduction in 1,4-cis content and polymerization yield.
