  • Patent number: 9018325
    Abstract: A nonmetallic compound having an ionic bond with a halide ion is used as a catalyst for living radical polymerization. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced, and it is made possible to prevent adverse effects of using a radical initiator (such as side reactions). The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor, etc. The catalyst can be applied to various monomers and enables synthesis of high molecular weight polymers.

  • Patent number: 7611888
    Abstract: The present disclosure provides a rotaxane compound that can be used to separate molecules within a linkage layer formed on a solid substrate of a biochip by a predetermined distance. The compound is represented by Formula 1, in which a compound of Formula 3 vertically passes through a cavity of cucurbituril or its derivative of Formula 2. It further provides gene chips, protein chips and sensors for biomaterial assays which use the rotaxane molecules to allow biomaterials to be immobilized on a linkage layer such that they are regularly spaced apart from each other by a predetermined distance.

  • Publication number: 20080293597
    Abstract: A sterically hindered quaternary ammonium composition is prepared by contacting a solvent having hydroxyl functionality, a halohydrin, and a sterically hindered tertiary amine, under reaction conditions sufficient to produce a sterically hindered quaternary ammonium compound. The reaction proceeds with excellent yield. The resulting compounds are particularly useful for inhibiting formation of hydrates in hydrocarbon reservoirs and pipelines. Novel compositions of matter include sterically hindered quaternary ammonium compounds conforming to the formulas C27H58XNO2 and C29H63XNO2, wherein X is a halogen.

  • Publication number: 20080234432
    Abstract: A method for making a monomer having an ethylenically unsaturated group and two or more quaternary ammonium groups per molecule, comprising: (a) reacting an excess of a monomeric reactant having at least one ethylenically unsaturated group and at least one tertiary amino group per molecule with a halohydroxyalkyl(trialkyl)quaternary ammonium salt, in an aqueous medium, (b) monitoring the pH of the aqueous medium from at least as early as the time when all reactants have been added to aqueous medium until completion of the reaction, and (c) adjusting the pH of the aqueous medium to and maintaining the pH of the aqueous medium at a value greater than or equal to 9, from the time, after all reactants have been added to aqueous medium, that the reaction mixture exhibits an apparent pH minimum until completion of the reaction.
