An improved amorphous metal composite and process of making the composite. The amorphous metal composite comprises amorphous metal (e.g. iron) and a low molecular weight thermosetting polymer binder. The process comprises placing an amorphous metal in particulate form and a thermosetting polymer binder powder into a container, mixing these materials, and applying heat and pressure to convert the mixture into an amorphous metal composite.

Amorphous metal composites

Certain aryloxyphosphonium salts have been found to be effective as curing agents for various cationically polymerizable organic materials, such as epoxy resins, when incorporated into such materials. The materials are found to be moisture curable coating compositions.

Moisture curable compositions and aryloxyphosphonium salts

The process comprises placing an amorphous metal in particulate form and a low molecular weight (e.g., 1000-5000) thermosetting polymer binder powder into a container, mixing these materials, and applying heat and pressure to convert the mixture into an amorphous metal composite.

Method of making amorphous metal composites

Aryloxyphosphonium salts

Interaction of ethylene glycol with a preformed polyesterimide resin at elevated temperatures forms mixtures homogeneous and clear at room temperature and also soluble in non-polluting solvents, such as monoethers of glycols.

Soluble polyesterimide resins

An improved substantially solvent-free process for preparing phthalate-moiety based polyesterimide resins, new resins prepared by the process, and substrates (e.g., electrical conductors) coated with compositions comprising the new resins are described.

Polyesterimide resins and synthesis thereof

Disclosed is a process for preparing oligomeric polyetheramide-acid by reacting an aromatic dianhydride component including an aromatic bis(ether anhydride) with an organic diamine in an inert organic liquid selected from methylene chloride, chloroform, 1,2-dichloroethane, and mixtures thereof with acetone. The oligomeric polyetheramide-acid is substantially insoluble in the inert organic liquid, in which the oligomer typically appears as a precipitate which may be recovered in powder or finely divided particulate form without need for grinding.
