摘要： A thermosettable, polymerizable resin composition comprising a polyepoxide and a polyisocyanate which is normally catalyzed by a basic curing catalyst for forming oxazolidone rings and isocyanurate rings or uredione rings is remarkably stabilized at low temperatures by incorporating a small amount of an organic electron acceptor, such as, picric acid, quinone, chloranil, or cyanoacetate ester into the composition. Since the specific electron acceptors effectively inhibit the polymerization of the reactive components in the composition at low temperatures, a shelf life of the composition is remarkably prolonged.

摘要： A novel thermosetting resin can be obtained by mixing 1 equivalent or more of a polyfunctional isocyanate per 1 equivalent of a polyfunctional epoxide and then carrying out a polymerization reaction of the mixture in the presence of the catalyst which forms isocyanurate rings and oxazolidone rings so as to enable the mixture to form 2 or more isocyanurate rings directly connected with oxazolidone rings through an isocyanate residues.The resulting thermosetting resin has excellent electrical, chemical and impact resistances and excellent self-extinguishing properties. Said resin is used as an electric insulating material.

摘要： An immobilized enzyme membrane for use at the working face of an electrochemical electrode is prepared which comprises an asymmetrical membrane integrally formed from a skin layer substantially incapable of permeating an enzyme therethrough but capable of permeating a gas and a liquid, and a sponge layer having pores containing an enzyme immobilized therein by crosslinking and which pores intercommunicate with one another throughout the sponge layer and provide sufficient porosity for retaining a necessary amount of the enzyme. The immobilized enzyme membrane contains a large amount of enzyme, has good diffusion and permeability, and has stabilized enzyme activity for a prolonged period of time. Additionally, there is obtained a quick response time and good analytical precision when the immobilized enzyme membrane is used at the working face of an electrode of electrochemical measuring instruments.
