To provide a method for producing a styrene resin having a syndiotactic structure, including performing addition polymerization of one or more of a vinyl aromatic monomer in the presence of a catalyst containing a half metallocene transition metal compound (A) having at least one kind selected from metals of groups 3 to 5 of the periodic table and lanthanoid transition metals as a central metal, a compound (B) represented by the general formula (1), and a compound (C) selected from at least one kind of an oxygen-containing compound (c1) and a compound (c2) capable of forming an ionic complex through reaction with a transition metal compound, the styrene resin produced having a transition metal content derived from the half metallocene transition metal compound (A) of 1.5 to 12 ppm by mass.

Disclosed are solid or semisolid compositions the including finely divided particles and a water-soluble matrix that dissolves and disperses the particles when in contact with water. Also disclosed are kits for reducing and/or inhibiting odor formation on garment. The kit include one or more containers, wherein at least one of the one or more container includes solid or semisolid compositions the including finely divided particles and a water-soluble matrix that dissolves and disperses the particles when in contact with water. An edible silver delivery system including the compositions is disclosed as are methods of delivering silver to a subject in need thereof.

The present invention provides a bio-electrode composition including (A) an ionic material and (C) a metal powder, wherein the component (A) is a polymer compound containing a repeating unit-a having a structure selected from the group consisting of an ammonium salt, a sodium salt, a potassium salt, and a silver salt of any of fluorosulfonic acid, fluorosulfonimide, and fluorosulfonamide. This can form a living body contact layer for a bio-electrode that is excellent in electric conductivity and biocompatibility, light-weight, manufacturable at low cost, and free from large lowering of the electric conductivity even though it is wetted with water or dried.
