Abstract
A process for the polymerisation of cyclooctadiene-(1,5) wherein cyclooctadiene-(1,5) is polymerised on halides of tungsten, molybdenum, tantalum, or rhenium as catalyst in the presence of bicyclo-[2,2,1]-heptadienes-(1,5) of the general formula (I) ##SPC1## as activator, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 denoting independently of each other, a monovalent hydrocarbon radical or hydrogen.
