标 题 :Process for the synthesis of crystallizable 3,4-polyisoprene and isoprene-butadiene copolymers having high vinyl contents
发明人：HSU WEN-LIANG; HALASA ADEL F
权利人:GOODYEAR TIRE & RUBBER
摘要:Crystallizable 3,4-polyisoprene and isoprene-butadiene copolymers having high vinyl contents can be synthesized in organic solvents to quantitative yields after short polymerization times by utilizing the catalyst systems of this invention. The 3,4-polyisoprene made utilizing this catalyst system is strain crystallizable and can be employed in tire treads which provide improved traction and improved cut growth resistance. This invention specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent at a temperature which is within the range of about -10 DEG C. to about 100 DEG C. in the presence of a catalyst system which is comprised of (a) an organoiron compound which is soluble in the organic solvent, wherein the iron in the organoiron compound is in the +3 oxidation state, (b) a partially hydrolyzed organoaluminum compound which was prepared by adding a protonic compound selected from the group consisting of water, alcohols and carboxylic acids to the organoaluminum compound, and (c) a chelating aromatic amine; wherein the molar ratio of the chelating amine to the organoiron compound is within the range of about 0.1:1 to about 1:1, wherein the molar ratio of the organoaluminum compound to the organoiron compound is within the range of about 5:1 to about 200:1, and wherein the molar ratio of the protonic compound to the organoaluminum compound is within the range of about 0.001:1 to about 0.2:1.
