Abstract

Polybutadiene having a predominantly 1,4-cis structure is obtained by polymerizing 1,3-butadiene in the presence of a catalyst comprising a lithium-containing component, titanium tetraiodide and a halogen salt of a metal of Group IIa or IIb. Suitable halogen salts, which are preferably used in anhydrous form, mentioned are the bromides and iodides of magnesium, calcium, strontium, barium, zinc and cadmium. The lithium containing component may be an organo-lithium compound, e.g. lithium alkyls such as lithium methyl and polylithium compounds such as trimethylene dilithium; metallic lithium and lithium alloys and their mixtures with organic lithium compounds or the reaction products of metallic lithium or lithium alloys with organic halogen compounds, which may, if desired, be produced in the presence of carrier substances such as graphite or aluminium oxides. Specification 822,742 is referred to.
