Abstract: 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 polydiene thus obtained is useful for tires and golf balls and as a polystyrene modifier.
