Zusammenfassung:	PCT No. PCT/EP96/01275 Sec. 371 Date Nov. 10, 1997 Sec. 102(e) Date Nov. 10, 1997 PCT Filed Mar. 22, 1996 PCT Pub. No. WO96/31543 PCT Pub. Date Oct. 10, 1996Catalysts comprising A) a rare earth alkoxide, a rare earth carboxylate and/or a rare earth coordination compound with diketones, B) an alumoxane and C) an inert, particulate, inorganic solid with a specific surface area of greater than 10 m2/g and a pore volume of 0.3 to 15 ml/g are excellently suited to the polymerisation of conjugated dienes, in particular butadiene, in the gas phase.
