Abstract
A method of producing polymodal cis-polybutadiene in the presence of an initiator obtained by mixing at least one organometallic compound as the first component and a second component containing titanium and iodine, the total amount of titanium being used in the range of 0.2 to 2 millimoles per 100 grs. Of 1,3-butadiene and loading a first quantity of said initiator in an amount that gives 0.02 to 0.15 millimoles of titanium per 100 grams. Of 1,3-butadiene and polymerizing 2 to 45% by weight of said 1,3-butadiene to a polymer having an inherent viscosity in the range of 6 to 20 and then adding the remainder of said initiator without adding more 1,3 -butadiene while continuing said polymerization to form a final polymer product having an inherent viscosity in the range of 2 to 5.
