摘要： High vinyl polybutadiene rubber is utilized in a variety of applications. For instance, high vinyl polybutadiene is utilized in tire tread rubber compositions because it provides both good traction and rolling resistance. The present invention discloses a technique for synthesizing high vinyl polybutadiene utilizing a molybdenum catalyst system. This molybdenum catalyst system can be utilized in aliphatic solvents with high yields of about 75% being attained. The molybdenum catalyst systems of this invention are comprised of (a) a molybdenum containing compound which is prepared by modifying molybdenum pentachloride, molybdenum trichloride, or molybdenum tetrachloride with an alkyl carboxylic acid or an aryl carboxylic; and (b) an aluminum containing compound which is prepared by modifying a trialkyl aluminum compound with a phenol. The molecular weight of the high vinyl polybutadiene being prepared can be reduced by modifying the trialkyl aluminum compound with an allylphenol, such as 2-allylphenol.

摘要： Metals from Groups I and II of the periodic table are commonly used to initiate the polymerization of conjugated diolefin monomers into polymers. The polymers formed in such polymerizations are terminated with the metal used to initiate the polymerization and are sometimes referred to as living polymers. Reactive end groups can be affixed to the chain ends of such polymers by utilizing the process of this invention. Such reactive end groups can subsequently be reacted with the backbone of other polymer chains. This results in the formation of a polymer having a reduced number of dangling chain ends. The functionalizing agents which can be utilized in the preparation of such polymers include hexachlorocyclopentadiene, tetraalkylthiuram disulfides, and chlorinated phenyl fulvenes.

摘要： Short fibers of syndiotactic 1,2-polybutadiene are utilized in making tires that have improved resistance against heat build-up and improved wear characteristics. The preparation of syndiotactic 1,2-polybutadiene in fibrous form has traditionally involved an extrusion and stretching step. However, the technique of the present invention circumvents the necessity of hot mill flexing and/or extrusion in making fibrous syndiotactic 1,2-polybutadiene. The present invention more specifically involves a process for preparing syndiotactic 1,2-polybutadiene fibers directly comprising polymerizing 1,3-butadiene monomer in the presence of (1) a catalyst composition which is comprised of (a) a cobalt compound and (b) an organoaluminum compound; (2) carbon disulfide; and (3) at least one member selected from the group consisting of liquid polymers and naphthenic oils.
