摘要： Pure syndiotactic 1,2-polybutadiene is a thermoplastic resin which has double bonds attached in an alternating fashion to its polymeric backbone. Films, fibers and molded articles can be made utilizing syndiotactic 1,2-polybutadiene. It can also be blended into rubbers and cocured therewith. Syndiotactic 1,2-polybutadiene can be made by solution, emulsion or suspension polymerization. It typically has a melting point which is within the range of about 195 DEG C to about 215 DEG C. However, it is often desirable for the syndiotactic 1,2-polybutadiene to have a melting point of less than about 195 DEG C. This invention discloses a process for preparing syndiotactic 1,2-polybutadiene having a melting point of less than about 195 DEG C which comprises: polymerizing 1,3-butadiene monomer in an aqueous medium in the presence of (1) a catalyst composition which is made by reacting (a) at least one cobalt compound (b) at least one organoaluminum compound, and (c) at least one conjugated diene; (2) carbon disulfide; and (3) at least one modifier selected from the group consisting of (a) 4-(alkylamino)benzaldehydes, (b) 4-(dialkylamino)benzaldehydes, (c) 2,4-di-(alkoxy)benzaldehydes, (d) 2,6-di-(alkoxy)benzaldehydes, (e) 2,4,6-tri-(alkoxy)benzaldehydes, and (f) 4-(1-azacycloalkyl)benzaldehydes.

摘要： The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.

摘要： Tires having white sidewalls are very popular in the United States and Canada. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative design on the sidewall thereof which comprises (a) applying the decorative design to the sidewall of a cured tire and (b) binding the decorative design to the sidewall by the application of heat and pressure; wherein the decorative design is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene or blends of SPBD having melting points which are within the range of about 70 DEG C to about 160 DEG C and from about 25 weight percent to about 75 weight percent of at least one polydiene rubber which is blended with said syndiotactic 1,2-polybutadiene, at least one pigment or colorant, sulfur, and zinc oxide.

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.

摘要： This invention reveals a very useful process for producing polybutadiene composed essentially of syndiotactic 1,2-polybutadiene in tetrahydrofuran comprising polymerizing 1,3-butadiene in said tetrahydrofuran in the presence of (1) a catalyst composition microencapsulated in a polyene product which contains (a) at least one cobalt compound selected from the group consisting of (i) beta -diketone complexes of cobalt, (ii) beta -keto acid ester complexes of cobalt, (iii) cobalt salts of organic carboxylic acids having 6 to 15 carbon atoms, and (iv) complexes of halogenated cobalt compounds of the formula CoXn, wherein X represents a halogen atom and n represents 2 or 3, with an organic compound selected from the group consisting of tertiary amines, alcohols, tertiary phosphines, ketones and N,N-dialkylamides, and (b) at least one organoaluminum compound of the formula AlR3, wherein R represents a hydrocarbon radical of 1 to 6 carbon atoms; and (2) carbon disulfide. This polymerization technique is very useful in the synthesis of syndiotactic 1,2-polybutadiene which will be used in articles for packaging, transportation, or storing of foods since it employs tetrahydrofuran as its polymerization medium.
