  • Patent number: 7060803
    Abstract: A metal complex-protein composite comprising apohemoglobin, apoheme oxygenase, apocatalase or apoferrin having cavity and a metal complex has a specific structure that the metal complex is received in the cavity of the apoprotein. The metal complex is prepared by complexation of a metal ion, which is selected from the group consisting of rhodium, ruthenium, and palladium, with a ligand. The metal complex-protein composite functions as a hydrogenation catalyst of an olefin in water. The metal complex-protein composite is thus effectively applied to hydrogenation of water-soluble subtrates and has enviromental advantages over organic solvents.

  • Patent number: 5874507
    Abstract: The specification discloses a method and additive for increasing the surface activity of non-polar polymeric materials, and a non-polar polymeric material exhibiting increased surface activity. The invention employs an additive of the formulaA-B-A.sup.1wherein each of the A and A.sup.1 blocks which may be the same or different has a number molecular weight in the range of from about 200 to about 1000 daltons and is selected from the group substituted and unsubstituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl and alkylaryl units derived from one or more esters, organic acids, organic halides or organic acid halides, and units derived from alkyl or aryl isocyanates or ester-amides. The B-block is a polyepichlorohydrin unit derived from a polyepichlorohydrin polyol having at least two terminal hydroxyl groups and having an average molecular weight in the range of from about 400 to about 4000 daltons.
