Zusammenfassung:	A PROCESS FOR THE PRODUCTION OF BUTADIENE PROPYLENE COPOLYMERS A process for the production of strictly alternating copolymers of trans-1,4-butadiene and propylene units by the solution copolymerisation of butadiene and propylene with vanadium-containing organometallic mixed catalysts, wherein vanadyl dialkoxy halides of which the alkoxy groups are branched in the 2-position to the oxygen atom are used as the vanadium compounds.
