A flame retardant solid electrolyte comprising an ion conductive polymer matrix having moieties capable of imparting flame retardance to the polymer matrix and ether bonds in the molecule and an electrolyte salt dispersed in the polymer matrix. The flame retardant solid electrolyte may be one which comprises a non-ion-conductive polymer matrix and a liquid electrolyte consisting of an electrolyte salt dissolved in a solvent therefor, which is dispersed in the polymer matrix. The flame retardance-imparting moieties are derived from halogen or phosphorus-bearing compounds.

Flame-retardant solid electrolytes

The invention relates to a method of producing imide bond-containing resins. The method comprises reacting a halogenated phthalic anhydride, a specific copolymer and a diisocyanate compound in an inert solvent in the presence of a quaternary phosphonium compound as a catalyst to give an imide bond-containing resin in high yield. The imide bond-containing resins provide flammable substances with good fire or flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the resins can be used as flame retardants in a broad range of application.

Method of producing imide bond-containing resins

The invention relates to a method of producing imide bond-containing compounds and flame retardants comprising such compounds. The method comprises reacting an acid anhydride with an isocyanate compound in an inert solvent in the presence of a tertiary amine as catalyst. The imide bond-containing compounds thus obtained provide flammable substances with good flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the flame retardants comprising such compounds have a wide field of application.

Method of producing imide bond-containing compounds and flame retardants

The invention relates to a method of producing imide bond-containing resins and flame retardants comprising such resins. The method comprises subjecting a halogenated phthalic anhydride, a specific copolymer and a diamine to dehydration reaction in an inert solvents to give an imide bond-containing resin. The resins provide flammable substances with good fire or flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the flame retardants comprising these resins have a wide field of application.

Imide bond-containing resins and flame retardants comprising said resins

Compounds useful as flame retarders for organic high molecular compounds are obtained by reacting a polycondensate of a halogenated phenol, e.g. a tribromophenol polycondensate, with a metal compound or organic compound having at least two functional groups capable of reacting with the terminal hydroxyl group of the polycondensate, e.g. an alkaline earth metal halide, an alkyl dihalide or an acyl dihalide.

Flame retarder for organic high molecular compounds prepared from

A granular flame retardant additive is provided comprising from 70 to 99.5% by weight of an organohalide flame retardant and from 0.5 to 30% by weight of thermoplastic synthetic resin as a binder. The additive is easy to handle and resistant to disintegration during transportation and mixing with fabricating resin pellets. Uniform distribution thereof in fabricated thermoplastic articles is achieved by simply co-feeding the granules and the fabricating resin to a fabricating machine.
