  • Patent number: 9034976
    Abstract: After a cyclopentadiene compound and a vinyl aromatic compound are thermally polymerized, the obtained copolymer is subjected to a hydrogenation reaction to form a hydrogenated product. After most of the hydrogenation solvent is separated by a solvent evaporation tank from the hydrogenated product, an additive separately prepared by dissolving an antioxidant is added to the hydrogenated product to form a mixture. While the hydrogenation solvent is a naphthenic solvent, the additive is prepared by dissolving the antioxidant in an aromatic additive solvent having the same carbon atoms as those of the hydrogenation solvent. Then, the low-molecular-weight component as well as the remaining hydrogenation solution and the additive solvent are separated by a thin-film evaporator from the mixture. The obtained molten resin is pelletized to produce hydrogenated petroleum resin pellets. The time for uniformly blending the antioxidant can be shortened.

  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

    Abstract: Unsaturated organic compounds are brominated with a quaternary ammonium tribromide or a quaternary phosphonium tribromide, especially when the bromination is conducted in a chlorinated solvent. A quaternary ammonium or quaternary phosphonium monobromide salt is produced in the reaction, together with some amount of quaternary ammonium or quaternary phosphonium monochloride salt. The monochloride salt is converted to the corresponding quaternary ammonium monobromide salt by reacting it with a source of bromide ions. The monobromide salt is then reacted with bromine to regenerate the quaternary ammonium or phosphonium tribromide, which is recycled into the bromination reaction. This process reduces the amount of chlorine that is incorporated into the brominated product.

    Abstract: Provided is a production method which can attain exfoliating treatment of graphite and a process of grafting a polymer onto exfoliated graphite simultaneously and thus makes it possible to easily obtain an exfoliated graphite-polymer composite material in a short time. A method for producing an exfoliated graphite-polymer composite material includes a step of mixing graphite or primary exfoliated graphite, a depolymerizable monomer of which the polymer is decomposed by heating to generate radicals and also to form a monomer or an oligomer, or the polymer A of the monomer, or a polymer B which forms radicals at a temperature close to its decomposition temperature to obtain a mixture; and a heating step of putting the mixture in a non-open container to heat the mixture to a first temperature range from the ceiling temperature or higher to the onset decomposition temperature or lower, or to a temperature higher than the first temperature range.
