An enzyme electrode comprising an anode, a cathode, an immobilized enzyme membrane, and an electrolyte, which is characterized in that said membrane consists of a dense skin layer having selective hydrogen peroxide permeability and a porous layer wherein the enzyme is immobilized onto the porous layer of the membrane and said immobilized enzyme membrane is arranged in the electrode so that the skin layer is faced to the electrode and the porous layer immobilized with the enzyme is in the position of contacting with the test solution. The enzyme electrode is used for the polarographic determination of a slight amount of components in body fluid, body tissue, foodstuffs, or the like without any undesirable hindrance with low molecular interfering materials without using any other specific means for removing such low molecular interfering materials.

Enzyme electrode provided with immobilized enzyme membrane

An unsaturated polyester resin composition containing titanium dioxide excellent in the stability of dispersion of the titanium dioxide and suitable for the manufacture of opaque, molded products comprising (1) an unsaturated polyester resin containing titanium dioxide consisting of an unsaturated polyester obtained from a high molecular weight saturated polyester containing titanium dioxide as the raw material and a copolymerizable monomer and (2) at least one compound selected from the group consisting of a hydroxyalkylamine (A) having at least one amino group and at least one hydroxyl group attached to different carbon atoms thereof, a polyoxyalkyleneamine (B), a mono- or dicarboxylate (C) derived from the compound (A) and a mono- or dicarboxylate (D) derived from the compound (B).

Unsaturated polyester resin composition containing titanium dioxide

A process for producing polyester resins, such as saturated polyester resin, alkyd resin and unsaturated polyester resin from polyester wastes, which comprises depolycondensing polyester wastes with at least one polyol in the presence of at least one titanyl oxalate compound and/or titanium tartrate compound and subsequently polycondensing the resulting depolycondensation product with at least one polycarboxylic acid or its anhydride or with at least one polycarboxylic acid or its anhydride and at least one polyol, optionally in the presence of at least one phosphorus compound.
