Superconductor-polymer composite materials comprise a matrix formed of a rmoplastic polymer and a superconductor powder dispersed in the matrix. The superconductor powder preferably has a composition RBa.sub.2 Cu.sub.3 O.sub.7-x wherein R is a rare earth metal and x is less than or equal to 1. The thermoplastic polymer matrix comprises a vinylidene fluoride homopolymer or copolymer. The composite materials may be formed as shaped products, sheets or films.

Superconductor-polymer composites

A solid polymeric electrolyte which is a two phase interpenetrating network f a mechanically supporting phase of a continuous network of a crosslinked polymer and an ionic conducting phase comprising a metal salt complexing liquid polymer which is a liquid poly(ethylene oxide), poly(propylene oxide), or poly(ethylene imine) complexed with a suitable metal salt. The mechanically supporting phase forms a matrix which supports the interpenetrating ionic conducting liquid polymer phase which provides continuous paths of high conductivity in all directions throughout the matrix.

Interpenetrating-network polymeric electrolytes

Polyethylene imine-metal salt solid electrolyte

A method of preparing anticholinesterase organophosphoro and organophosph-fluoridates, e.g., GB in situ by mixing a phosphorous ester in an aprotic solvent with a solution of tetraethylammonium in the same solvent.
