标题 :Synthesis of elastomeric high trans-1,4-polybutadiene
发明人：CASTNER KENNETH FLOYD
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention is based upon the unexpected discovery that elastomeric trans-1,4-polybutadiene can be made by utilizing a catalyst system that is comprised of an organocobalt compound, an organoaluminum compound, a para-alkyl substituted phenol, and ortho-phenyl phenol wherein the molar ratio of the para-substituted phenol to the organoaluminum compound is within the range of about 1.2:1 to about 1.8:1, and wherein the molar ratio of the ortho-phenyl phenol to the organoaluminum compound is within the range of about 0.7:1 to about 1.3:1. Accordingly, the elastomeric trans-1,4-polybutadiene made by the process of this invention does not need to be heated, such as in a hot-house, before being used in making rubber stocks. This invention more specifically discloses a process for synthesizing elastomeric trans-1-4-polybutadiene by polymerizing 1,3-butadiene monomer in the presence of a catalyst system that is comprised of an organocobalt compound, an organoaluminum compound, a para-alkyl substituted phenol, and ortho-phenyl phenol, wherein the molar ratio of the para-substituted phenol to the organoaluminum compound is within the range of about 1.2:1 to about 1.8:1, and wherein the molar ratio of the ortho-phenyl phenol to the organoaluminum compound is within the range of about 0.7:1 to about 1.3:1.

标题:Synthesis of cis-1,4-polybutadiene rubber in presence of cobalt containing catalyst system
发明人：CASTNER KENNETH FLOYD
权利人:GOODYEAR TIRE & RUBBER
摘要:It has been determined that 1,3-butadiene monomer can be polymerized into cis-l,4-polybutadiene rubber utilizing a cobalt-based catalyst system which is comprised of (a) an organocobalt compound, (b) a trialkylaluminum compound and (c) hexafluoro-2-propanol. The use of this catalyst system results in extremely fast rates of polymerization. The molecular weight of the cis-1,4- polybutadiene rubber made utilizing this cobalt-based catalyst system can be regulated by conducting the polymerization in the presence of 1,5-cyclooctadiene. This present invention more specifically discloses a catalyst system which is particularly useful for polymerizing 1,3-butadiene monomer into cis-1,4-polybutadiene, said catalyst system being comprised of (a) an organocobalt compound, (b) a trialkylaluminum compound and (c) hexafluoro-2-propanol. The subject invention further discloses a process for synthesizing cis-1,4-polybutadiene rubber which comprises polymerizing 1,3-butadiene in the presence of (a) an organocobalt compound, (b) a trialkylaluminum compound and (c) hexafluoro-2-propanol.

摘要:This invention is a process for synthesizing aliphatic 1,3-diols in one step by hydroformylation and hydrogenation of oxirane, carbon monoxide, and hydrogen employing a catalyst comprising a cobalt carbonyl compound and a cocatalyst metal compound ligated with a ligand in a ligand to cocatalyst metal atom molar ratio in the range of 0.2:1.0 to 0.6:1.0, optionally in the presence of a promoter, where recovery of product is preferably accomplished via water extraction of a diol rich phase from the bulk reaction mixture. The process modifications can, particularly in combination, be beneficial with respect to product recovery, catalyst recycle, and overall economics of a one-step process for producing aliphatic 1,3-diols.

标 题 :Synthesis of trans-1,4-polybutadiene having controlled molecular weight
发明人：CASTNER KENNETH F
权利人:GOODYEAR TIRE & RUBBER
摘要:Trans-1,4-polybutadiene is normally synthesized utilizing transition metal or rare earth catalysts. However, molecular weight control is difficult to achieve with such catalysts and the molecular weight of the polymer produced is frequently much higher than desired. By utilizing the catalyst system and techniques of this invention, trans-1,4-polybutadiene can be synthesized continuously to a high level of conversion with molecular weight control being possible. This invention specifically relates to a process for synthesizing trans-1,4-polybutadiene by polymerizing 1,3-butadiene monomer in the presence of a catalyst system which is comprised of an organocobalt compound, an organoaluminum compound and a para-substituted phenol with molecular weight being controlled by conducting the polymerization in the presence of at least one dialkyl sulfoxide, diaryl sulfoxide or dialkaryl sulfoxide. Such polymerizations can be conducted on a batch or a continuous basis. In the case of continuous processes, it is normally desirable to conduct the polymerization in the presence of carbon disulfide as a gel inhibitor.
