Abstract

A PROCEDURE FOR PRODUCING POLYBUTADIENE, characterized essentially by carrying out the polymerization of 1,3-butadiene in the presence of a catalyst consisting of aluminum of triisobutyl, titanium tetrachloride and a diene containing from 4 to 12 carbon atoms, diethylene diene being added and iodine, obtaining polybutadiene with a 90% excess of the cis 1,4-form, the polymerization being carried out by forming a rubber polymer in which the butadiene is maintained in a hydrocarbon solvent in the presence of catalytic material comprising an alkyl aluminum, titanium tetrachloride and a diene containing from four to twelve carbon atoms, the catalyst system consisting of said aluminum alkyl, titanium tetrahalide and diene, the ratio of the aluminum alkyl to the diene being not greater than 5'3/1, the polymerization being carried out at a temperature comprised in the range of between approximately 4.5 and 71 degrees C., preferably between and 45 and 50 degrees.
