  • ALLYL ALCOHOL COPOLYMER AND PRODUCTION METHOD THEREOF
    Publication number: 20100286354
    Abstract: The invention relates to an allyl alcohol copolymer comprising structures represented by formula (1) and (2) as monomer units. (In the formula, R represents an aliphatic hydrocarbon group having 2 to 20 carbon atoms, which may be branched or include a cyclic structure). The copolymer of the invention is excellent in compatibility with various resins, adhesiveness, electric insulation, low water absorption, thermal stability and surface active effect.

  • Process for oxidizing carbon-carbon double bond and process for producing oxidized compounds
    Patent number: 7038069
    Abstract: A method of oxidizing a carbon-carbon double bond wherein the compound having the carbon-carbon double bond is suppressed, the unreacted compound is separated from the reaction product, and thereafter the thus obtained unreacted compound is again used for the oxidizing reaction; and a process for producing an oxidized compound utilizing such an oxidizing method. When this method is used, an intended oxidized compound can be obtained with high selectivity and high productivity.
