Abstract
A process of producing a butadiene polymer, in which at least 75% of the units are in the cis-1,4 configuration, which comprises polymerizing butadiene in the presence of a catalyst system formed by mixing a first component having the formula MeCln (OR) 4-n with at least one second component selected from the group consisting of (1) a compound with the formula AIR'R''I and (2) a mixture of an organic aluminum compound with the formula AIR'R '' R '' 'and a compound containing reactive iodine, where Me is a metal of group IVb of the Periodic Table, R and R' are hydrocarbon radicals with 1 to 12 carbon atoms. R "is selected from the group consisting of hydrogen, hydrocarbon radicals having 1 to 12 carbon atoms and oxy-hydrocarbon radicals having 1 to 12 carbon atoms, R '' 'is selected from the group consisting of hydrogen and hydrocarbon radicals with 1 to 12 carbon atoms and n has a value of 1, 2 or 3, the ratio of aluminum to Me being between 1 and 10 on a molar basis and the amount of said compound containing reactive iodine being between 0.5 and 1.5 moles per mole of said, organic compound of aluminum.
