  • Patent number: 8183326
    Abstract: A polymer includes directly bonded aromatic pendent groups and at least one moiety defined by one of the following formulas >N—N?CR1R2 or —N?N—CR1R2— where R1 and R2 (a) are independently H or a substituted or unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, allyl, aralkyl, alkaryl, or alkynyl group, or (b) together form a substituted or unsubstituted alkylene, alkenylene, cycloalkylene, cycloalkenylene, or arylene group. The moiety can be attached to the polymer through one or both of the two open bonds and, where it is attached through only one bond, the other bond attaches to a hydrogen atom, i.e., the moiety is at a terminus of the polymer. Such polymers can be used to provide compositions that also include particulate fillers.

  • Publication number: 20120048446
    Abstract: The present invention achieves increased filler interaction by incorporating a small amount (a few units per chain of rubbery polymer) of a conjugated triene monomer, such as alloocimene, randomly throughout the polymer chain of a rubbery polymer or at the chain ends of the rubbery polymer. The incorporation of the conjugated triene monomer leads to the formation of a polymer containing highly reactive conjugated diene units. These conjugated diene units can chemically react with carbon black leading to superior reinforcement. Alternatively, these conjugated diene units can be used for functionalization of the polymer with silica interactive/reactive groups using Diels Alder reactions. This functionalization of the rubbery polymer can conveniently be conducted in a mixer, such as a Banbury mixer, a mill mixer, or the like.
