  • Patent number: 8552144
    Abstract: Redox reactions that occur at the electrodes of batteries require transport of both ions and electrons to the active centers. Reported is the synthesis of a block copolymer that exhibits simultaneous electronic and ionic conduction. A combination of Grignard metathesis polymerization and click reaction was used successively to synthesize the block copolymer containing regioregular poly(3-hexylthiophene) (P3HT) and poly(ethylene oxide) (PEO) segments. The P3HT-PEO/LiTFSI mixture was then used to make a lithium battery cathode with LiFePO4 as the only other component. All-solid lithium batteries of the cathode described above, a solid electrolyte and a lithium foil as the anode showed capacities within experimental error of the theoretical capacity of the battery. The ability of P3HT-PEO to serve all of the transport and binding functions required in a lithium battery electrode is thus demonstrated.

    Abstract: After hydrolyzing a phospholipid bonded to a molecular end of a natural rubber, a compound having a polar group reacting with a hydroxyl group is condensed with a hydroxyl group contained in the phospholipid-hydrolyzed natural rubber to thereby obtain a modified natural rubber in which a polar group is present at a molecular end. The modified natural rubber thus obtained in which a polar group is present at a molecular end is used for a rubber component of a rubber composition, whereby a rubber composition in which carbon black and silica as fillers are bonded to the rubber component to enhance a reinforcing effect and which is excellent in a low hysteresis loss property and abrasion resistance to a large extent is obtained. An enzyme or an alkali is used for hydrolyzing the phospholipid, and a condensing agent is used for condensing the polar group-containing compound.

  • Patent number: 7928159
    Abstract: A process for providing interaction between particulate filler and a functionalized polymer involves a composition that includes at least three components: (1) a polymer that includes a functional group including an acidic cation of a primary or secondary amine functionality, (2) a material including a functionality capable of reacting with the acidic cation, and (3) particulate filler. The amine functionality from (1) is allowed to interact with (3) after being neutralized by the action of the acid-reactive functionality from (2). The process is useful in the formation of vulcanizates and articles made therefrom.
