Abstract: The present invention relates to polymers, rubber compositions, and tires. In some embodiments, the present invention relates to polymers comprising repeat units provided from at least one amine monomer. The amine monomer can be an amine styrene monomer. Examples of amine styrenes monomer are provided. In other embodiments, a polymer can be made from the copolymerization of at least one amine monomer and at least one monomer that is used to make synthetic rubber, such as at least one conjugated diolefin monomer. These polymers can be terminated with a terminating group, including, for example, those having a hydrolyzable group. Rubber compositions can be made from the above-described polymers. Tires can be made from the polymers or from the rubber compositions.

Abstract: An apparatus is disclosed for measuring the permeability of an anode of a solid oxide fuel cell. The apparatus includes a specimen container, an air reservoir and a recorder. The specimen container includes a can and a cover. The can includes a tunnel defined therein and a cavity in communication with the tunnel. The anode can be disposed in the cavity. The cover includes a tunnel defined therein and a bulger inserted in the cavity and pressed against the anode so that air can penetrate the anode and travel into the tunnel of the can from the tunnel of the cover. The air reservoir is in communication with the cover. The recorder measures and records the pressure and temperature of air in the air reservoir before and after the air is introduced into the specimen container from the air reservoir.

Abstract: The invention includes a siloxy-imine functionalized rubbery polymer, which exhibits good reinforcing characteristics and filler dispersing effect, a method for making, and a rubber composition including the same. In one embodiment, a process for manufacturing the functionalized rubbery polymer includes polymerizing a conjugated diene monomer using an organolithium compound as an initiator in a hydrocarbon solvent. Next, an active terminal end of the polymer is reacted with a functionalized terminating agent, represented by the general formula: RCH?N(CH2)XSi(OR1)YR23-Y, ??Formula (1) wherein R represents a group consisting of an aryl or substituted aryl having 6 to 18 carbon atoms, or a heterocycle or heteroaryl having 3 to 18 carbon atoms; R1 and R2 each independently represents a group having 1 to 18 carbon atoms selected from an alkyl, a cycloalkyl, an allyl, and or aryl; X is an integer from 1 to 20; and Y is an integer from 1 to 3.

Abstract: 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. It is generally preferred to synthesize syndiotactic 1,2-polybutadiene in an aqueous medium by suspension or emulsion polymerization utilizing a cobalt-based catalyst system. This invention is based upon the unexpected finding that certain substituted benzoic acids can be employed to deactivate such cobalt based catalyst systems.

Abstract: 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. In such applications, sometimes it is beneficial for the syndiotactic 1,2-polybutadiene to have more than one melting point. This invention discloses a process for preparing syndiotactic 1,2-polybutadiene having at least two different melting points 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 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 CoX.sub.

Abstract: 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. It is generally preferred to synthesize syndiotactic 1,2-polybutadiene in an aqueous medium by suspension or emulsion polymerization. In such aqueous polymerization techniques reactor fouling and particle size control problems are frequently encountered. This invention is based upon the unexpected finding that reactor fouling can be greatly reduced or eliminated and that particle size can be regulated by conducting such aqueous polymerizations in the presence of a controlled amount of dissolved oxygen which is within the range of about 0.01 ppm to about 4 ppm.
