Abstract

Butadiene is polymerized using a catalyst comprising (A) an organometallic compound having the formula RnM where M is aluminium, gallium, indium, beryllium, mercury, zinc or cadmium and R is an alkyl, cycloalkyl, aryl, aralkyl or an alkaryl radical containing from 1 to 20 carbon atoms per molecule and n is equal to the valence of M, and (B) a member selected from the group consisting of (1) titanium tetraiodide, and when M is aluminium, (2) mixtures of titanium tetraiodide and titanium tetrachloride and (3) iodine and a titanium halide TiX4 where X is chlorine or bromine. The butadiene is contacted with (A) to form an admixture therewith and then the admixture is contacted with incremental amounts of the (B) component. The term "incremental" covers either stepwise or continuous addition. Long lists of suitable catalyst components are given. The polymerization is usually carried out in a diluent, lists of which are given. In a batch process, the reaction mixture is inactivated by treating with an alcohol or water and the polymer is then separated and may be further purified. In a continuous process the total effluent is pumped to a catalyst-in-activating zone where an alcohol, for example, is added. If necessary a precipitating agent may then be added and the polymer separated from the diluent and alcohol which may be re-used after being fractionally distilled. A polybutadiene having a cis-content of 85 to 98% or higher may be produced. In the example the catalyst is triisobutyl aluminium, titanium tetraiodide and titanium tetrachloride and the solvent is toluene.
